I had a nice time with this! I really found the simple combo of top down shooter + mastermind engaging and wanted to beat it. I wasnt able to beat it because the zombie seem to just get way too tanky, on my firts playthru a basically endless swarm busted into the lab and each zombie took more than a whole "clip" of the gun to kill so i was overwhelmed. On the second playthru I tried to kite them like CoD zombies but they kinda warp to you and stick to you when they are attacking which made it hard. I also laughed when the first scientist you talk to ran around panicking and actually pushed me back into the horde of zombies! Probably unintentional but still! Over all nice work and you've got a great foundation here!
