A simple yet fun game! I like the fact that you have to use switching between day and night to your advantage. Not being able to proceed until you switch correctly is a good challenge. The graphics and aesthetics are pretty consistent although it would be nice to have a little animation of sorts when the diamonds are collected. The 8-bit music and pixelated sprites give it a nice retro feel. The mechanics are simple, however I feel that the space should be used for jumping as it feels more natural that way. The game follows the theme pretty well since the game itself is 2D and there is a level of duality between switching from night and day. Overall an excellent little game! Thanks!
