I know that the palette is between two colors, but that is not 1-bit.
The difficulty progression of this makes the game feel bland and uninteresting very fast, you need to first expose the player to more before making him face weird sets of non-stop obstacles. A game can be hard but still slowly expose the player so he gets the hang of it before having to face a challenge.
Felt like a bland platformer, and I also don’t understand where Light and Dark fit in this.
…Although, I do admit that there could be space for interesting gameplay by exposing the player to some smaller, more repetitive tasks, before making him face big non-stop ones. Changing the enemy movement patterns could also help a lot to make the gameplay more engaging.
