Very fun game! The puzzles are implemented really well, I always felt so satisfied when I figured something out!! The difficulty felt fair, nothing seemed too easy or too challenging. The artstyle is super cute as well, I especially loved the character animations.
I did come across a bug where resetting some rooms places you in a position where you're stuck between two locked doors with no pressure plates to get you out. Of course the 'T' reset unstucks you from this, but I still feel you should be placed outside of the locked rooms. Also another thing I noticed is that you can't push blocks while walking. It's a super small thing, but it makes the controls feel a little unresponsive.
I had a lot of fun playing through this!! I hope my feedback wasn't too harsh haha. I'm excited to see more of this!
