I liked this one, it was silly, got to the point quickly, and was short but sweet!
First of all I loved the UI, it has obtrusive 90's FPS feel like System Shock or Marathon.
The sprites were nice, though perhaps a bit too nice and stylized for this jam. I liked how the skull eyes turned red when detecting the player, and for some reason the games colour scheme and animations especially on the final boss reminded me out the old Lucas Arts Outlaws FPS.
The attack felt a bit unsatisfying, though having made a number of games for this jam with awkward combat I'm not gonna hold that against it too much. The real issue I had with it is that it felt impossible to get a hit in without being hit yourself, and while this could easily be healed with the spooky soda, it typically meant I just had to stand around drinking for a while. So the combat loop didn't really feel all that engaging.
But aside from that, this was some great spooky SBIG stuff! Good work!
