That's a lot of good ideas! Scene transitions are super, introduction of the new elements is smart. 

I found some problems too :) The sounds pop (maybe a poorly edited one or bad import settings), they don't play if I fall on the ground without jumping first. I suggest changing lightblue background with a grey one, so the eyes will have a rest! You could add an info how many keys you need to collect.

I really like the particles and that save/load system!

Great puzzles! good job :)

Please consider rating my game too ^ ^

What a nice puzzle game, the sounds though... Amazing music!

the puzzles were really good. The only thing that I found to be frustrating, is that you never know, what a button does and you have to play every puzzle many tims over again.

great puzzle game. the game does a very good job at teaching you the mechanics one at a time so I was never that confused and the puzzles were fair but still challenging. The checkpoint system is a cool idea and creates some interesting gameplay especially the load jumps were a lot of fun. the later levels felt a bit repetitive because they had very similar layouts but the game was still very enjoyable. the game also just feels great to play: the movement is responsive and smooth, the particles look nice and the music is very good 

Oh boy those keys are hard to catch hahah

The checkpoint placing is a great idea, really make the whole difference in the game

Nice job \o/

Very nice game, I loved the music, it was fun and enjoyable, responsive movement, and a great concept, excellent job, WOWIEE!!! :D

Your game is very fun and interesting! It was a pleasure to spend time with exciting gameplay and beautiful music!

Pretty great game! Love the clean visuals and sound, cool checkpoint mechanic as well! Nicely done.

Great game with great movement!

The game gets better the more you play!

Keep up the great work!

Really solid! Controls felt really great, although, just because I can tell you really went for it, I'm gonna be a little extra nitpicky and say that the platforming jump delay was just a little too late (so you could jump while feeling entirely off a platform, bit too noticeable) and the particle effects for movement were in the way a little too much. But overall, so much fun, great level design, absolutely epic.

This game is really great. Great audio & music and puzzle design, especially load jumping and clinging onto blocks from the bottom. Really nice game. Visuals could be improved but I cant say too much cause I didn't work on my visuals either xD

5 stars all the way; really great submission - loved the music and the puzzle design (load jumping?!  that's such an awesome idea)

Very nice game, I loved the concept of load and save, goood job !!

Very well done puzzle platformer with an actually unique feature of save/load. good job. :)

This was a really nicely done puzzle platformer! I liked the puzzles and the main mechanic!

The last few puzzles felt a little repetitive, and I've found a most likely unintentional bug. :P

If you hold jump beneath a platform you just keep jumping.

Overall I enjoyed the game, its a good idea, executed well. :)

I like the concept alot of manipulating loading points, and in most levels in works well. Visuals and sound are great too, simple and effective. If there's one critisism I would give is that sometimes it is unclear which button closes which door, which in one or two puzzles made it a bit too much trial-and-error in my opinion. Overall it's a really nice game with a great concept. Good job!
