Cool game. I played the downloaded windows version. Very long and elaborate level for a game jam game. A couple small things I noticed. After killing the purple enemies they still moved around a bit and I was not sure if they were dead or not. This was only an issue when several of them bunched up together. Also the green plants were not attacking me and I was just able to stand next to them and shoot them. Not sure if this was intended or not.
I really like how you are able to upgrade your weapons and armor. Really cool feature give the time frame for a game jam. Good job over all.
