Chromagun is a portal-clone through and through but with bad puzzles you can permanently fail just by pressing the wrong button and very bad writting.

I've only played some of them, but the puzzles are just thoroughly boring and uninspired. They revolve around painting walls in order to attract these flying balls so they hover over the correct triggers. They are incredibly simple-minded, tedious and fragile. Failstates that force you to reset each chamber can be reached by the press of a button almost from anywhere.

The "humour" follows the same exact structure as Portal. Enter chamber, disembodied voice spews some dialogue, silently solve puzzle, disembodied voice congratulates you. The jokes are delivered by a GLaDOS emulator whose decent voice performance is not enough to elevate the terrible material.

Toss it into the incinerator.
