This game has a nice game play, with interesting level design and names, it's short and pretty to play, I really liked it.
The art is simple and with a minimal color pallet of 3 colours (also adding the alternative pallet, which in total would be 6 [counting white] ), and it's kinda intuitive, highlighting objects with orange, and solids with black (same with the changing colour option, in which black is blue and white is yellow), when you stop the time, everything reverses their colour, black goes white, and orange objects go white too, that means that if you can step on them too, the only thing that doesn't change are the spikes, which gives the player a subtle advise that they still hurt the player in stop and normal mode, great work!, also, the screen shakes added that little touch it needed, the only thing that I want to say though, is that it could had a more creative design, abstract design is good, but I think that with something more special it would be greater.
Only sounds, but they fit nice with the game, when you jump, when you lose, when you go to the next level, stopping time, etc, (I don't know a lot about music and audio honestly, but I'll try to describe the feeling) the curve of the note feels right to the actions, a down banishing sound for when you lose, a power outage sound like when you stop time (which also combines with the default color pallet as everything goes black), and an ascending sound or positive transition when you get to the end of the level, all of them are pretty good! (maybe I'm being to analytic about them but I wanted to point them out hehe)
I guess i had seen before the mechanic of stopping the time in a platformer, I don't know where thought, here it's nicely implemented, and it felt intuitive, the player control feels good, maybe the sloppy feeling of being near a round edge it's normally bad, because if the player stands in one of them, they slowly fall, but in this case they are pretty good, when you jump into a solid, the round edges can help you slide on them and that feels nice in this game (also they combine and blend nicely with the artistic style), the names of the levels are pretty funny, sometimes is easier to identify them with those names even, for example, when I read that you can make a super jump with space & W, I tried to beat the game without stopping the time, I completed all the levels until "weee", and also beaten "huh?" the first time without stopping the time, that sounded like a nice challenge too.
Overall, I really enjoyed this short platformer and it's pretty good for being made in a game jam! (a fact that I realised moments after ending the game), I want to see more of your work!
Keep it up and souled!
