Using 1 and 3 on a keyboard was a bit awkward for this kind of game. Using the arrow keys would have been much better. I wanted to play more but due to a glitch in the game, I cannot afford any fuel after completing a level. You should probably have a simple game over screen and not a menu screen that states I need to buy fuel and gifts to continue with no way to back out other than to refresh the page. It could have been better.
