Game looks great! Sprites are really polished and cute! My only gripe at all was the speed of the players. I wanted them to move around just a bit faster. Other than that I still had a lot of fun! Some good puzzles in there! We had similar ideas on the platformer with multiple abilities! Kudos!

Nice job with all your hard work for the jam! Here's my in-depth review:

Design [2/5]: I'll start with the positives: the concept of controlling one character at a time to get a princess through an exit door makes for a very nice puzzle game ripe with opportunity. I think you have a nice cast of characters that are all creative and unique.
Having said all of that, I thought the execution was weak and the level design is incredibly frustrating. It is possible to get completely stuck on the very first level if the Knight falls into that first pit (happened to me). At first, I realized I could no longer collect the coin at the bottom left of the screen, but that frustration turned into a huge eye-roll when I realized I also could no longer finish the level. To make matters worse, there's no obvious way to restart the level, so I just had to refresh the browser page and start the game over. In general, I think the level design is incredibly frustrating, and the fact that there's no way to restart the level after making a mistake means that the best players will be punished the hardest for making a mistake (seems backwards to me). If I make it all the way to the last level and make a mistake, I'll have to restart the entire game just to see the ending, which is a poor design choice. It's too easy to become stuck in the middle of a level, and I think that should have been brought into consideration (especially in the earlier levels).
That was my experience when I first played the game, but it wasn't until I came to this comments page and read through some of the other comments that I realized you actually can restart the level. However, you have to open the options menu and click through a couple of buttons to do it. Aside from that being a clunky way to handle restarting (a simple press of the 'r' button on the keyboard would have done just fine), the player is never told about that in the game. There is a tutorial screen, but it mentions nothing about how to restart a level. Since dying or becoming stuck is such a strong possibility, it's really important that players know how to restart the level, so that was a huge problem for me.
I also faced some other minor annoyances while playing. I was frustrated that your character always faces to the right whenever you stop moving, even if you were moving left. This can become a problem for any of the characters with an attack, since attacking left means you have to be moving and attacking at the same time.
Again, I want to say that this game is a nice concept in theory, but I was so frustrated by the level design and the lack of an obvious way to restart the level that I couldn't finish playing it.

Adherence to the Theme [5/5]: You have multiple characters, but you only control one at once. Nice job!

Originality [3/5]: As nice as this game is conceptually, I've seen it before in a game called Thomas Was Alone. I don't want to dock you too much, considering that's a relatively unknown indie game, but the idea of a puzzle platformer with multiple characters that you control one at a time is not completely original.

Overall, I can tell you've put some nice effort into this project. The game looks nice, it's an interesting concept, and it's (mostly) bug-free. Keep working at games and I'm sure you will improve as a developer in time!

It's really nice. The sprite art looks really nice and the core concept is pretty good. The physics are a little too floaty and I wish there was an easier way to restart the level.

Cool! Nice idea and really polished overall, with all the UI and ideas. Reminds me a lot of The Lost Vikings. I do feel like the gameplay needs some tuning though, it felt like there was some collision issue that prevented my character from jumping sometimes.

Keep up the great work!

Nice! Really feels well done and the music made me feel like a hero!

The idea is really nice and the execution is great. It took me some time to realize which character is the princess. The jump is a little bit float but it is still good. The variety of characters is really nice and the level are really enjoyable. Great work.

Kinda short, but sure it's interesting!

Nice gameplay and visuals, wouldn't be bad if expanded and made a full game.

It's a pretty fun idea and the game looks good, but I'm missing some player feedback.
For one it's a shame there's no sound effects for deaths and fire and such, and some things are a bit surprising. In the last level for example I was certain I had to do something with those two mushrooms, and the little rock on the ledge that turned out to be a bomb was a nasty surprise.

The game also controls a little too sluggish imo. Making all the characters just a little faster would be better I believe. All in all fun concept, but it needs a little more meat on its bones (and a spelling check. A few hints such as "princess" vs "prince" are confusing and the game page says skills are used with E while the game itself says right mouse button).

Pretty cool. Would be nice to be able to swap characters using 1, 2, 3, etc. to keep the  momentum of the game rather than having to click on their icon only because it feels like it slows the game down Solid entry

The web version is very laggy but still playable. Great gameplay and really interesting idea, keep it up!

Nice entry! It looks and sound very well. As already mentioned a direct reset of a level, without opening the menu would be great. Also the witch at the end is actually cool but makes also the other 3 characters useless. But however, well done!

Befeore even starting i was HIPED cause of the music and i love the pixel art. My onlie conplain is the pacing of the game it's kinda slow to move BUT BREAT FOR 48 Hours!

This is visually pleasing and has epic music to keep you going! Seems very polished and I love the small detail of being able to zoom in and out. Nice job!

Great Idea! I played a game with a a similar concept called "Quantum Entanglement", which was also made for this game jam. You should check it out!

Very cool idea. I'll second the "please don't let me get stuck so easily on level 1" comment, but add that the only reason it bothered me so much is that I wanted to explore the idea more.  :)

Nice work. however, I've stucked at the first level with a knight. -_-

Hey man

Nice game. Are there really only 3 levels? I would like to play more. What are the coins for and why is there no pickup sound?

The concept reminds me a little at the LD43 winner total Party kill.
