Thanks for playing my game, let alone taking the time to comment. You're absolutely right about the speed, I never could work out how to increase it over time. I might have misread the requirements so I submitted the game with a 84*48 window resolution by default, and then created the means for players to scale it up by changing the value in 'assets/scale.txt'. I play it on the maximum 10, personally. Anyway, this was my first game jam submission, so I'm just really happy to have submitted something complete.
Thanks again for taking the time!
