I'm not sure how much further I'll develop this idea but at the very least I'll probably do some sort of post-jam version of it with various fixes and small enhancements. Yeah, you're completely right about repairing. There was meant to be a more obvious indication on the UI that repairing was happening but it was one of the smaller things that remained unticked on the to-do list at submission time! And, yes, there were also meant to be two other enemy types but again I just ran out of time. Thanks for playing! :)
