I played a bit more tonight, with more luck! The looting mechanics are satisfying and swapping between pistol for looting and the ak (with rarer ammo) for defending felt nice. I’m not sure if I missed something, I did the loop of looting and returning to defend a few times and only a few slimes spawned each wave. Grenades make quick work of them!
The locations and unique loot are good too, this has a lot of the things I love about survival type games in a unique and satisfying little toybox. Looking forward to more!
