I suggest increasing the pickup radius for coins, I just literally drove under one, and if you miss one even by like an inch, you have to turn all the way around.
Yea a shop would be nice at the end, maybe something like a little store that displays three items and they change after every battle. Good game though, 9001/5. :)
Lol, I think you should change hp to stamina, it gives people the wrong idea when they start the game and lose 1 hp each time the bar gets full, sorta like, "OMG I'M GONNA DIE IN LIKE 2 SECONDS, HOW DO I STOP IT!?!?!" At least thats what I thought. :)
Controls were to easy to figure out. :/
If arrows don't work its obvious what does and comon, making a letter stand out and the name of the level? I personally think the game shoulda been harder. >.<
Anyway, 5/5 :D
