SO SO SO SO GOOD!!!! There's so much variety, every weapon has a different strategy! Imagine this with upgrades! I'm silently squealing at the thought of that.
Thank you for that comment, because you really enjoyed the game apparently :D
2 more hours and upgrades would have been implemented. The idea was that after each wave you could choose one door and it would give you an upgrade. That would have made the game even better :D
