Chain Reaction (PC)
Открыть все: Используйте следующее слово как пароль: core
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.
