While waiting for the latest update to roll in out of boredom/not needing to sleep, I followed Rock Paper Shotgun's suggestion of playing Ir/rational, which is basically the bastard offspring of Portal's plot and pure logic. It's advancement by deductive reasoning- my Critical Thinking A Level got me through it in the end (knowing logic notation helps on the final level). You might experience issues with the drop-down bug- the menus will sometimes fall over text since the author had to second guess where the text gaps would sit. The other exe might improve it, but I found the original one to be better but not perfect- I had to guess the conclusion of one argument based on where the plot was going.
Give it a go
