This a poorly drawn webcomic about a man who has lived in Hell and decided that he does not like it there.
Unfortunately for him, the only way out is through a gauntlet of bizarre games: some are deadly, some are absurd, all of them are unfair.
Yes it looks like it was drawn in MSPaint. That's because it was - the simplicity is only sometimes part of the joke.
The comic (tries) to show a mix of comedy, horror, and strategy. The comic is about survival, and whether individuality can matter in a place designed to destroy it at all costs.
This is not a theological hell, but something worse in a number of ways; it is bureaucratic, endless, and meaningless by design. Characters fight for reasons that range from validation to hatred. The main guy, Jack, tries to prove that meaning can exist even when the universe seems to reject it ouright, and his existence is asserted through his will to survive.
ROTG is a comedy about hopelessness, and the hope that comes with it.
This is a series of three-panel comics that observe and mock philosophical musings that do not impact the lives of the mindphreaks that think them, or anyone else.
It is a lot more light-hearted than ROTG, and instead simply points out the pointlessness of particular thoughts that everybody has, but nobody can do anything about. To summarise in a single sentence:
Mindphreakings is about thinking of better things to do.
