I'll toss up a couple of mine.. simple 2d stuff, and nothing complete and ready to release.. problem is I get most of em to 80-90% and then get bored and move on to something else.. ugh.. =(

Kollectiv - new puzzle game that has most of my attention, using game state and particle system..

Toadder - Frogger clone.. 2 playable levels at this time.. still need to do the painstaking artwork and finish the other levels.

Starskimmer - 1st XNA game.. got moving asteroids, controllable ship via gamepad with acceleration, parallax scrolling and got bored.. you can shoot, but you cant die and cant kill anything..

Suu-ey! - pretty much done.. needs menu's, powerups, some better collision detection on the fence obstacles.. infinite levels.. pretty much 100% playable though..

Forum Lurking - neverending..
