I just beat it :)
Here's my feedback:
- I think the mechanic fits super well with the theme.
- I liked the music and the sound effects, they added to the whimsy vibe.
- I liked the player running animation, the character looked good.
- I think the player controls could use a little tweaking maybe, the acceleration was a bit slow. Still definitely playable though.
- The mushroom things that change your size weren't super visible, maybe they could've been a bit bigger?
And above all, congratulations on finishing something and submitting it, there is always room for improvements, but actually making something is how you get better and learn :)
