Game is simple and looks like it was made by "freshly baked" developer. But I do not say it was bad. Honestly, I really enjoyed exploring an environment. If I may, I would leave you some suggestions what to improve in the future:
- flip camera controls, so when you move mouse to the right you look to the right
- add sound effects and maybe some particle effects when player dies, I can really make a difference
- add some ambient sounds or music to create better atmosphere
- don't forget to add quit button when creating desktop game, so player will not be forced to alt+f4 it
- try to give player some instructions what is an objective of the game (by leaving instructions or making obvious signs what things do)
But all in all, I liked this game. So good job :).
