The twist was a very fun idea, however I felt like something was lacking. For a metroidvania it was very linear, while for a boss simulator it was not very boss-like with 2 pretty identical melee moves and a jump. Really this is one of those games that needed more time in the oven and more refinement to the formula to become good (like switching your alliegance every screen transition, and balancing not making one side too strong so that you can have an epic final battle, I'm imagining a small scale war where robots take over the ship, while the bugs reclaim it piece by piece)
