Wow! This is an incredible entry! I'm stunned by the amount of content here. This was a fun challenge. That said, there are a number of pretty serious things that are currently detracting from the game:

1. Please please please allow full screen, or at least a larger window. The tiny view was pretty difficult. 

2. The controller mapping is kind of weird. Right at the start, I could not figure out what button to press on my xbox controller to get out of the main menu. There doesn't appear to be any button; you have to press 'e' on the keyboard. That's fine, but it's a little hairy in-game too. The most annoying thing was that pressing the left-thumbstick on the gamepad pauses the game. When playing this game I realized how much I unintentionally press the left thumbstick. I kept pausing in the middle of the most intense sections.

3. In-game guidance is kind of lacking, especially when it comes to controls. I had to just press a bunch of buttons to figure out how to use the moth light power (which is an awesome powerup, by the way). Another example: after getting "dive" I had no idea what that meant. The player can now dive? Is that a special move? An attack? Did not occur to me that it referred to water. 

4. In some places, visibility is an issue. Many times I just did not see the smasher blocks because they don't stand out very much and in some cases, are hidden off screen. Also, in some cases it wasn't clear what was background and what was solid.

A few more minor things:

1. Boss fights were pretty great though only the final boss was a real challenge (at least for me). Final boss took me a long time to figure out because I didn't know what rays caused damage and which ones did not (another visual ambiguity issue). 

2. I was not a fan of the way shooting is locked into the direction you're pressing when you start shooting. I'd rather shooting change the direction with your change of direction, unless a button is held (a la Axiom Verge). 

3. I also had no idea I could shoot vertically until I stumbled across it. 

4. Final boss also tripped me up because I had no idea that dashing made you temporarily invincible. 

That's a lot of criticism but honestly this is the most impressive game I've played so far this jam. Well done! Thanks for making it. 

Simply the best!

Music, graphics, backgrounds with weather, traps, enemies, bosses, story, difficulty balance, UI with map and items - everything in place and top quality.  

Along the way I made some notes, my personal list of things that could make this game even better if it is possible at all:)

• I  miss fullscreen mode very much in browser play. The game dimensions are pretty small for me, and immersiveness also suffers when I see browser window.
• Jump feels a bit awkward, maybe a bit slow, idk, anyway I get used to it finally
• Falling stone trap is poorly visible in one place because of hp bar, I'd also prefer I could step on top of them like lifts, they don't look dangerous on the upper side
•  

• Big ghost is pretty static, first I thought it's a bug he doesn't react in any way on me appearing in the room
• Fall of texture beyond the left-top wall, and under the big ghost between lamps. Also, on top of the map when climbing walls I bump into invisible ceiling, I'd prefer some visualization of it, like where it is roof or spikes there.
• Some checkpoints are invisible. I was never sure where I'll be respawned. Luckily, more often it happened where it was really necessary and not only on the visualized checkpoints. In general invisible checkpoints do a good work, I just didn't get fully the system of mixed explicit and implicit checkpoints.
• It was a great surprise to me I can dash and shoot vertically! I almost gave up proceeding just because I didn't know I can dash in other directions. Maybe I missed tutorial message there? I discovered it by accident trying to push black boxes (they look pushable) to unlock passage. Also, dash doesn’t move without pressing arrow. What is the purpose of it? Maybe invulnerability? I didn't try it, just a guess, otherwise I wish dash by defaul pushing me in the direction of sight.
• clock hands in the tower show impossible time:) Maybe it's part of the story, then I just didn't get it:)
• long dialogs are not skippable before retrying battle with red

Thank you for such a great game!

This game is very well made and a lot of thought has clearly been put into the mechanics, great job!!!!!

My only criticism is of the ambiences and music I felt were empty at times and could have made the expereince a bit more enjoyable, still amazing overall tho!!

Really incredible work. I am amazed at how polished your game is. Well done!

Controls felt a bit off, but this is a great game overall. One of the best of this jam so far
