Dear ootc, your game is very nice. The music and the environment it' fun. The only things I found to improve (for me, of course) are:
1...the controls (I found it challenging to pilot my "car"), but could be that I do not understand so well how to drive it (isn't so intuitive, at least for me)
2...the ambiance is a little repetitive and simple (only bombs or coin) and could be better can interact with more items.
But the main feeling is positive, congratulation.
PS: in my test, the "car" is all the time at the bottom f the screen (could be because I don't understand well how to control it), but it could be better to move it a bit up.
