I reaaally dig the presentation of the main scene with the train itself. The sound of it speeding up to insane levels is also really well done. :) I wish mini-games to refuel it and to get extra sentry cars were a bit more satisfying, but hey, game jam! :D
I think there are some bugs as well. 1. If you don't wait for the pattern to disappear before starting to click on green tiles, the game gets confused. 2. I missed "Simon says" mini-game once, and every subsequent attempt failed immediately (until I left that screen and returned).
Nice job whipping this up for the game jam. :)
