Thanks for the feedback, I'm glad you had fun with it! I think some more variety to the enemies would be pretty cool, yeah. I had a few other concepts in mind, but that deadline is intimidating, Haha.
The repair shop is a common thing being mentioned. I agree I should have made it more clear on how to access it and I'll play with some solutions for that. As for picking up where you left off when you get back to maintain the flow of the game is better too, yeah. My thoughts on sort of resetting everything has two purposes: firstly, that it plays with the theme a bit more to start off slow and "turn up the heat," when the game picks up. And secondly, it is kind of like, you are in enemy territory and then leave. While you're gone the enemy is rebuilding back up their defences, so when you get back you have to punch through their mine field and turrets. But I think it would have been more fun to just jump back into the heat. Thanks again.
