Very interesting game! As for release it's pretty cool.
But there's one problem: weak strategy requirement. All you need to do is upgrade gains and door to +- 6-7 level and then make 3-5 turrets with 2-3 boosters and you already won. Keep upgrading things until monster die or time's up. With this strategy you can beat the game at single.
I hope this game won't be abandoned and will have more monsters and locations. Very cool things will be co-op with rooms that have at least 2 doors connect with other rooms. You'll have to relay on your teammates.
