Really cool game, congrats! In my game, there was an engineer that I could not move and he was not doing anything at all, so I think it's a bug.
The SFX were great, the background is really cool, the combat animation + art is definitively more than I was expecting for a 10 days game jam.
If you're considering in keep implementing the game, I would try to create some more cool mechanics. The first one I think would be cool it's giving specific skills for each character of the crew. For example, the guard could handle a monster in an 1 vs. 1, and the engineer could repair the leaks in less turns.
