The first thing I've been working on for a while but not much time really, just an hour or so a day, is a tile-based platformer. The most recent thing was springy platforms, kinda like trampolines.
Platformer
Easy controls:
Left/right to run, Up to jump, Up + left/right when on a wall to wall jump.
Still glitchy but I'll get round to fixing it.

Next is a very old game, very similar to the above one, with some playable levels (and a save game feature). I might possibly combine them sometime soon.
Platformer 2
The idea in this one is to get the stars to Unlock the electric doors, then get to the exit.
Controls:
left/right to move
Up to jump
R to reset
P to pause.
Space to enter doors

I also have a tower defence game on the way, but that's not really at a stage to be shown, it's all muddley code for now with bits working and bits not!

Finally I've recently started working on a physics based bumper boats/racing game. That I have a billion ideas for!
Bumpers Boats
Arrow keys to move (click the screen and move around) the blue ones target you for now, in the game they'll have a goal to reach (checkpoints or whatever in a race)
