Great idea, really great! Very fun too! At some point it gets kinda boring but when it came Thomas the train at full speed at me, I got my eyes blazin, pure adrenaline hahahah! Anyway, it is really fun and original. After the jam, try making something even bigger! I was thinking about making a big level with a lot of platforms and obstacles coming, and you have to survive, sometimes power ups would spawn at a random point in the level, and make a lot of different scenarios, get it? I would be really fun, and maybe a co op feature, dude it would be really funny!!!
Anyway, good job on the game, I loved it! Be sure to check my game and rate it as well!
