Wow! This is a simple but fun game. I like the background art. Did you do that yourself? I couldn't play it for long because the arrow keys on laptop suck, but I can still appreciate it. Maybe think of adding the up arrow key as a jump key. I think a lot of people like doing that instead of the space bar(including me) but I still really like it. I hope you succeed with this fun game and have fun doing it ;)
