Very well made for 3 days of development!
Well done including checkpoints. I was afraid of dying and losing all my progress before I knew they were there. After dying once and learning about them, it made me want to take the risk to explore the map more and actually get all the coins.
I really wish there were sound effects. They add a lot of life to a game.
I think the night vision is interesting, but I feel it needs something more mechanically to really make it feel as the main aspect of the game.
It's a very nice platformer for 3 days of development. Keep it up!
