Thanks for playing and thanks for the feedback! The enemies have set spawn points, the idea is that they are coming through windows I haven't added yet ( and a staircase in the middle), but based on the current level tiles it definitely just looks random. I want to come back to this game later down the line to add bigger/more levels but am looking to wrap this version up pretty soon. Agreed that cannon fellas are more fun, the melee enemies are mostly fodder at the moment.
Which weapon do you wish you started with?
