Nice gameplay! I watched your YouTube video too, I'm glad you chose the tile-based movement. I also liked that the mechanics were simple and easy to understand, didn't need a tutorial for them. Didn't know those blue tiles were fuel and that you died from the rocks, but it only took one time to learn that. Same with the mushroom effect. I also appreciate how the difficulty rose steadily.
Criticisms/Suggestions:
There could have been some more hazards than rocks and mushrooms (or maybe I just didn't get far enough...).
I think there was only one level. That wasn't a big problem though, because the game was challenging enough.
