I'm not too picky as to what kind of game its, but I do like metroidvania style games. If you think you can get more done in 2d then we can certainly go that rout as well. Also, your 3d in the katamari style game you made seemed pretty badass to me.
Thanks, the katamari game was originally a bit messy before I made it pull the pieces toward the center (link). I have an idea for a metroidvania fps game. I can just use really simple 3d models and textures. Is there a better way you want to communicate, like with skype or discord? We don't necessarily need to do a voice chat.
