Nice sound design (good use of SFXR/BFXR) and aesthetic. The jump is a little clunky, but I really liked the gravity mechanic and the variety between level designs. 

Fun, easy to play and understand but challenging enough. Simple graphics and music but suiting well the puzzle-platform genre. Funniest game and best design I have tested so far !

among my bets past timer...

Very solid little game.
Like the pixel art, the level design, the game feel it delivers.
I think it's quite completed that I can't give any advice.
Great work!

Very good implementation of different mechanics!

I've finished the game and it was really fun :)

Great execution! The jumping feels really good!

This game is really fun! I beat it and I like the variety of mechanics.

We also took on the idea of only having one jump! https://itch.io/jam/gmtk-2019/rate/462090

I absolutely love the design. It's SO simple but it works SO well. Dangerous things are red, the player is white, the level is dark, very nice contrast. The controls are also pretty good. The level design is fantastic as well.

Great job in implementing so many mechanics!  Awesome entry.

Very good game. Visually pleasing, good sounds and terrific difficulty curve. I would say the player is a bit slidy, but that might be on purpose. I loved how many objects you put in the game!

Loved the aesthetics and art! Very well executed puzzle game.

Great job!

I adore the game, neat, well polished with decent level desig. Well done!

Quite fun and work well ! I like the graphics too !

Interesting idea! Really like the gravity buttons :)

I finished it! Nice feel and response to the controls!

Fantastic game!

Great job, love the art/music

The up/down moving platform is bound to player movement?  Is that intentional ha?

Nice

Great Level Design!
