This is seriously impressive for a jam game. The retro Quake/Doom style is awesome, and the fact that you got a co-op multiplayer extraction/wave defense game working in a week is wild. I really liked the old-school visuals, the rail gun felt great, and I could see this being really fun with a group.
The gameplay was a little confusing at first and could maybe use some clearer direction/UX, especially around the code mechanic, but once it clicks it has a really cool vibe. Great work - this is one of the more technically impressive entries I’ve seen.
