The 7 Deadly Sins level set is a set of progressively difficult platforming levels.
The platforming is straight-forward and tends to focus on raw platforming mechanics as opposed to RNG, combat, and the use of tools/weapons.
These levels are meant to be played solo, and can be found on the PC version of BattleBlock Theater under the arena community theater, or it's workshop link.
