Melee attacks are definitely on the Todo list :D I had envisioned some super cartoonish crazy chainsaw that can be used in exchange for stamina.
Level Design I think will be the next logical step after getting the core function of the weapon loadout / ammunition pickups and random ammunition spawns.
I think I posted the Trello for this project on the main page. I didn't really think about setting up any place for folks to chat on it. We will see if many people download it etc :D
I was thinking the first 'Real' level would be something like a barnyard that would offer haybales and the barn and other things from a barn for obstacles to hide / and use for tactical advantage etc.
I think maybe having a "tag" game mode might be something I would like to work on in the future as well (taking in your last comment)
