Chain Reaction

Chain Reaction cheat codes: 
The password 'core' will unlock everything. The choose own music and
maybe the skip levels features will only work if you start a new game
with them switched on. The glowing traces game is a quick 10 level game
that's quite easy, and the tetris game, which can also be accessed via
coder.exe in the chain reaction folder (the access code is 15432) is
way too slow and has no drop key or any special features at all, but
as an extra it's nice.
