It was very pleasant to play, although on the first level where the other color was introduced, due to it being red I didn't even consider it being a color that could be used to draw, because red denoted a closed exit before that.
The movement speed is holding back the enjoyment a little bit too, but the lo-fi makes up for it, you can't get mad at a game that has lo-fi music.
Creativity... well... we did the same concept of the dice/square based puzzle game... although our dice has literal faces and also holds items, the numbers didn't seem to add anything in these levels, but maybe in harder levels it would take a lot of planning to always choose the highest number while also optimizing the route.
10/10 presentation, although it's an interesting choice to have it 45° perspective but controlled by the arrow keys... however it never actually impacted my gameplay, which I find interesting.
