Thought it was a pretty cool romp! I didn't feel particularly challenged if I kept moving. It seems like the monstor attack is too small. Was fun for a few minutes which makes it a great gamejam submission!
It was fun to have the "train" theme manifesting as becoming a weapon here. I felt that was a unique take on the theme, though it was definitely a bit hard to control and I would have liked to have been a train for longer (at the cost of filling up a bigger bar)
Bonus points for the wide input support of controller and k&m!
