Hey, sorry it took me a while to finally find the time.
I really liked the voice over!!! It was very fun to listen to. I think everyone who has ever made a game can relate to what you are saying. The bugs that keep coming back and not giving up is something we all know very well :)
Sadly I got stuck twice at the same place and had to watch your video. I think it is the same spot another comment mentioned, right in the middle. When you write "should I kill them all?" I did not really understand what to do. I tried to solve the level with the signs that say "- 1" instead. I shot all monsters except one and kited them through the arches hahaha.
So what is the meaning of the minus one signs? Please tell me they have some use. That part almost drove me crazy.
Overall I really enjoyed the game. The humor was exactly my taste and I think it fits the theme very well.
