Nice game!
Suggestions:
A darker theme/dark corners, would make it more scary
As would limited viewing angle (e.g. 120 – upgradable)
Limited ability to look around corners
Done!.. in 49 minutes. The first 32 minutes I spent hovering over the top left corner. Build 3 collectors and as many reactors u got room for on the plateau. Leave room for 3 blasters on the plateau
