Cool little game!
Graphics look good and I like the clouds. The mirror looks a little bit buggy so maybe there's a way to make it smoother. There are a lot of tutorials on this one.
Audio is fine. I liked the music and the vibe it gave me. Your game use some sound effects to make it even more polished.
Gameplay feels a little fit weird. I didn't know what to do actually. I randomly jumped up an arrow and glitched out of the world, then fell in a hole with and landen in a door opening. And finnaly did something in the mirror room. The ending was also very strange. After that I tried to find the legit way but could't find it. Also the movement feels a little unresponsive, it feels like walking on ice. Further more I liked the idea of an infinity room and finding your way out of there.
User Interface could use some more polish but for a game jam that's not that big of a deal.
Overall a good game. It's not because there's a lot of feedback that you made a bad game! I'm just here to help you improve your game. Either way well done!
