The game was great but it can be improved by fixing this issues:
1. The quit button doesn't work.
2. The player gets stuck on the walls.
3. There is no fall damage. (without fall damage, the game doesn't feel realistic, if you know what I mean)
4. There is no background music
5. The animations are not that good.
The game was more like a documentary than a real game and was too short (these aren't cons because game jam games are supposed to be short but if you are planning of making a polished game out of this, I suggest you make the gameplay longer. A good game overall which can be made into a polished product.
