very well made but still could use a bit more development. The music is pretty good for seemingly being origonal, The graphics are fine for what they are and the controls are decent. But the main things that you need to work on are the folowing
(1) Some of the pillars can generate too tall making it impossible to jump over.
(2) The collision detection is a bit janky and sometimes makes you stick to walls
(3) There is no background, if you add something there you can bring alot of variety to the stages
(4) The music is not long enough for the loop to sound natural. To fix that all you need to do is extend the song itself
(5) Try to add some way to regainb fuel so the game does not end in 2 minutes.
Just some suggestions on how to improve it.
