Hi mate! This is a well executed game, didn't find any issues while playing it. Your rotation mechanic is cool, too. The character is looking great :)
I've noted some points:
- No audio, you could probably generate random noise to make some footsteps and sounds when collecting an item for example. Without sound a game feel quite empty.
- I wanted to see more mechanics into the Maze like your mushrooms, doing different things to make me going crazy (change of the colors, inverted controls, darken place...). I think it can be annoying after playing a bit to not have different feedbacks from the collectibles.
- I didn't like the water tiles. The other tiles are okay and consistent, but the water is looking way too different.
Thanks for this game btw, had good time playing it!
