Hey Rohbert, once again, thanks for checking out my game!
Just came to see what you are doing here; looks like a really fun recourse managing puzzle game. Played it a bit with my Xbox controller and felt really good to control. Just a bit confusing using the start key to swap between modes (thought I had to use all blocks for the game to start in first level).
Also found a bug where you can walk out of the level by moving down at the start.
The color swap is a cool feature! Did you accomplish this with shaders? Also, which engine did you use to make this if I may ask?
