I scored 14029 after some tries.
If the yellow doors or brown tiles do anything then I didn't figured it out.
I like the music and the game is fun. It feels unique enough while that's a gameplay loop you could find on NES.
I generally just chose an easy path to a couple of green tiles and then left because it works, which doesn't feel that satisfying. I feel like to prevent that and also to prevent someone who's good at the game from never getting to die then the game could speed up between levels and there could be a minimum score to reach in a level before being able to jump to the next.
