Great game! I loved all of the hypno content, and it was easy and intuitive enough that I could beat it without using any countermeasures. I can't wait for what else may come in future updates.
If you were to add anything new to this (excluding more levels which I know will come eventually), I'd like to see a secret ending where: if you're tranced and all your team is sheep-ified but you still beat Dr. Woolhead while under, then there's a scene where Scott slowly morphs into a sheep while announcing "mission accomplished," the whole team announces their loyalty to Woolhead, then they let her go free/retrieve her from her crash site and we get an bad-end version of the win screen.
If you're down to use my ideas for the scenario/image I'm imagining: 1) a shot of all of them in the processing center, 2) them flying off into space as her personal zonked squadron, with maybe an internal shot of at least Scott's ship showing him zonked by pop-ups on the monitors, or 3) a bad end version of the existing win screen, with Woolhead there hypno-domming them.
I do understand you're focus is on adding more to the game, so ignore this if it would take time away from developing new content.
