That was wicked, really liked the train movement mechanic.
I found it difficult to tell when I was taking damage, since the effects on damage look similar to projectiles. That and the tight level spaces made it quite tough to get into a flow while dodging bullets.
Feels like there's quite a lot of replayability in this because of how differenly the guns perform. I would have liked to have some influence over which guns got added to my train... that way I would have been able to experiment with different builds.
Really cool jam!
