Really nice concept and good onboarding/tutorial. I think it's a pretty good proof of concept that just needs some custom art and juicy feedback. The controls work fine but I think some redundant keys wouldn't hurt. I.e. scrollwheel up and down to change the size (current up/down arrow), space to continue (current enter), etc. I also wonder how it would feel like if you can transition more smoothly between small, normal and big form? What if you could lerp between them, visually but also regarding the different properties/"skills" the 3 states have? It might be worth exploring. In any case, great game!
