Wait, uh...which tiers give us access to these releases? It looks like it's just the $15 tier (sadly outside my budget :c), but the wording here confuses me.

If you just want the most recent builds of the game, you can just pick the lowest tier (3USD). The higher tiers give you more goodies like streams about the game's development (5USD), unpublished prototypes, short stories (10USD), and access to play test builds (15USD). These are just some of the most noteworthy benefits, you can find more on our Patreon page.
