The levels are good and can be challenging at times. But there is some room for improvement:

1)Firstly, it needs an instructions screen, or atleast a menu screen. Launching the game throws you right into the game, which is kind of abrupt.

2)The graphics could be a lot better

3)There are some minor glitches, like the player gets randomly teleported back to the start position. I am not sure what the third point is, and that brings me to the first point back again, you should add a tutorial screen.

Leaving these one or two things aside, its a nice game challenging game, and I really like what the shift key does, and how it helps solving certain challenges. Nice job.

Thanks a lot for the feedback :)
You got yourself back at the start of the level if you die ( falling or touching red-blocs) and if you get out of power (yellow bar on the top), you can also use 'R' to reset the level by yourself. I don't know if it's what happend to you.
It may indeed need to be clearer, I'll try work much more on those points next times.

A lot of varied levels and good core mecanics, especially the gravity slowdown one.

But there's a big problem that makes platforming really frustating : when you hold down shift and a direction, then you release the direction, it reset the level, making some jumps very thigh and unforgiving.

Also the lack of music and SFX is a shame, but that's not to be expected in such little time.

Overall it seems like a very well thought of platformer and some debbuging will help it become more accessible.

@mrjotubes thanks a lot.
There was indeed a glitch and i'm so sorry for that, was some kind of wrong optimization compilling settings.
I'm sorry you had to play with those bug, it was working well on my pc :/

I uploaded the good exe so now it'll be good.

I uploaded my gameplay of this game on youtube, you can find it here

Thanks for being part of the stream :)

Good mechanic and interesting gameplay. Good job

Interesting mechanic with gravity control. Good job :)

Quite a neat puzzle-ish platformer, good core mechanics concept and truly different levels make for an enjoyable experience. Well done!

Great ideas and level design, could use an overall polish in many aspects(animations, movement, sounds, etc...).
Given enough time could become an amazing game with ease.

Nice and fun idea, but needs more polishing - some jumps are pixel perfect, sprites flicker a little bit and also movement is a little bit floaty.

Thanks a lot for all your advice guys!

The floating mechanic was pretty tough to figure out, but once i did, the game was great.

Explanations would have been great.
Sounds and Musics too, if you want to create sounds really easily you can use bfxr or some kind of tools next time.

Other than was already mentioned above. Excellent mechanics application during the advance of the game. Explanations are a little bit off viewing sight of the player but not a big issue. Maybe some music and sound would add the game feel needed.
