Hi! Thanks for your feedback ! I appreciate it.
Yeah, I guess putting everything together at once wasn't the best thing to do, but this was still some 'last stand' going on, that's why it was meant to be like a final battle being repeated .
And yes, the first about three stages are pretty much the same. But after that, things do change. If you're bored, try using the C key to instakill all the enemies. I believe the fourth stage is where things get interesting with bosses and stuff.
Hope you enjoy!
