Had fun. It was cool seeing the astronaut get stronger. Losing spawn area definitely hurt. It's a nice penalty. It would have been nice to see the astronaut's progress when it deactivates the spawn areas. I love how clicking and dragging spawns a ton of aliens quickly and the sound when they pop too. It's so satisfying.
I haven't managed to beat it without cheats yet. Thanks for providing one so I can see the end :)
