I loved this game. The tower defense phase was fun, though sometimes it felt like the weapons weren't shooting where I was trying to aim. I liked the little elevator intermission scene, it's very cute. Exploring the laboratory after the first few defenses was a fun race against the clock, and I'm not sure when I unlocked the jetpack to traverse, but that definitely made it a lot easier to reach the upper areas!
My only wish is that there was a way to sell unwanted weapons in later laboratory stops, I had so many that I couldn't keep them all on cooldown in the end.
Wonderful game, nice work!
