I just submitted LASER LOOTER. It's a Twin-Stick ASCII Shooter.
Since each ASCII character is 8x8 pixels, the game could only use 8x8 ASCII characters. Tough.
I'm still hoping to add some title music and many more little details to the rooms.
The final version for the Game Jam has been updated. I balanced the difficulty and made minor modifications to the levels to make it more fun. I also added stars to the level transitions and fixed a whole bunch of glitches.
So far my best "score" is getting all of the items with 4 lives remaining. The best one can do is get all items and have 7 lives.
