Crittatest is a noncanon testing location for the ::/FRAME/ roguelite section. There are 2 versions of Crittatest, the earlier of which previously only accessible via corru.works' Kofi but made publicly available after the release of EP3ADD2. Both versions omit the stage and escape sequence.
Crittatest 1
Crittatest 1 is the first available version of Crittatest, it is completely unlike the actual roguelite section in the game. A notable difference is the map, where you have to travel to specific nodes, or to create your own, to battle; battles work the same as the regular game, and they pay out in shells (up to the max of 6), components (humors), augments, and items (ranked from common to rare). Another difference is the shell modification page, where a new option is available: passives; passives add extra health and augments depending on the humor used, and act like the Action impulses in the final version. Another major difference is the Firmament being called the Wall as well having its stats decreased.
Some other minor differences include some modifications being missing, like Wild Surge and such, and the shop being slightly different, where you can buy humors as well as having the options from the regular game.
Crittatest 2
Crittatest 2 is the second available version of Crittatest. This version changes passives in Crittatest 1 into impulse caches. It is almost exactly the same as the version seen in the game except with testing dialogue after beating the Firmament.
