So I spent a good amount of time on this (it's my first game), and was excited to find that you can run Greenfoot games on Android (with Droidfoot). However, my game does not seem to want to run on mobile devices. I receive heap-space memory errors after a few compilations on my PC, so I'm thinking it must be due to a memory issue in my game. Any pointers to help improve the games performance are greatly appreciated! http://www.greenfoot.org/scenarios/12530
