Haven't had time to post lately, but I'm still working on Etain Falls Forever (intermittently). I removed ammo drops from bosses and instead have made two alternate heroes that incorporate slightly different playstyles.
Thinking about future projects, there's one I really want to do in Unreal Engine 4 or Unity 5, which would be a multiplayer coop FPS style game inspired by a board game. The biggest obstacle for me in solo creating 3D games has always been the art, I'm not amazing at making 2D art either, but it's easier to fake it.
I'd love to do a multiplayer 2d dungeon crawl kind of game, but most popular engines don't excel at 2D and networked multiplayer at the same time:
GameMaker: Studio - Supports 2D really well out of the box, network multiplayer is only slightly supported
Unity 5 - Constant changes to "experimental" 2D offerings make using it a crap shoot, new UNet multiplayer might be viable. Requring third party 2D packages opens a whole new slew of compatibility issues (if you've noticed, as I have, a lot of coded products on their asset store become vapor ware quickly).
UnrealEngine 4 - Easily the best network multiplayer offerings out of the box, but 2D options are often "experimental" as well.
