Is it too harsh to reset the whole progress when I touch the grey region? Otherwise, it would be a nice game.

I'd say this game needs a little bit more polish. There are controls given for shrinking and growing, but not for which keys are needed for movement. The maze part of the second level is tough because the movement is floaty and glides some. I like the concept though!

fun and simple, the second level was quite frustrating to play XD

definitely a few moments where i was super close to completing it then hit the walls.

overall a great first game!! :D

Not bad for your first game. It would be nice if you added sound effects. The second level was a bit difficult as it wasn't clear that you couldn't touch the wall and it was frustrating to have to go back to the beginning.

Quite a cool concept ! I'dd suggest adding one intermediary shrinking size, to complexify the game a little bit. Also, some boxes in the level are a bit misaligned, which makes it look a bit wierd. Appart from that, I liked the difficulty ! You could also consider adding some checkpoints (maybe some collectable coins ?) to avoid teleporting back the player right at the begining. I'd also suggest adding a final victory screen and music, for final touches :)

Anyways, good job !

its not bad. Just hard
