BitLadder

I'm making a space shoot 'em up for my #F256K2 while participating in a week long Game Jam. The twist is that you go across computer video game ages and the graphics and sound scale up the "Bit Ladder" with you as you buy upgrades.

some chips might not be available depending on your machine. Both K2 and Jr2 support everything. a Jr will only support PSG, and SID if you have them installed. a K will support PSG, SID and OPL3.

WASD to move 

right ALT to shoot 

X to stop moving 

space bar to cycle eras 

F7 to toggle music (it has to die down before it's able to start again)
