It's kinda hard to see where the game was going since I don't fully understand the concept and the controls behind it.  But I did manage to figure it out enough to "win" by getting small enough.  Plus I mean seeing a Godot game is always a welcome sight :3.  Anyway though I feel like the fact there's no instructions ingame or on the page is a bit unhelpful.  Since it took me a bit to figure out exactly what to do, and I still don't really understand it after doing it.  So some finer feedback:

• A tutorial obviously like I said, though also obviously jam time + self restrictions as you said.  It would definitely be welcome though.
• A clearer setup, and exit would be nice.  Since currently I seemed to be small enough to exit a lot, but it never actually let me?  Which was sorta weird.  So maybe making the size needed clearer somehow?  Possibly with a number or an image of the player at that size next to it?
• The enemies being unable to enter the "shrink zone" lead to some interesting strategy of moving them away from where I was attempting to go.  So maybe you could capitalize on that depending where you take the game.  Mess with the strategy a bit by having enemies that just defend, or harder to trick ones.  Maybe immobile ones?  Stuff like that.  Cause that was definitely an interesting portion.  As well if you went down that route you could add a soft timer by having the player shrink every few seconds while in the "shrink zone" so that they can't just stay in it forever, they do have to be in danger from the enemies.  

Hello, I think your game is not being rated because only have a download version and not playable in browser and some people do not want to go through the zip file hassle. I rated your game so not you have another! good luck! If you feel like, check my game and rate if it deserves it! Thanks
