Man, as of now, the current build of the game is... kinda not great. I don't want to say crappy, as it's not, but it's not great. For one, you need to collect 10 crystals, but to get them you need a picaxe, and to get one of those you need EXTREME luck it seems, as thus far for my past two playthroughs I've only managed to get TWO so far, while all the rest have been keys and or sigils... which don't really do anything after a certain point.
Honestly, the game suffers heavily from a lack of a store, as you can't buy anything, you can't use any of the abilities oddly, and there aren't that many H-scenes. Overall, I'm going to recommend we wait until they have a little bit more here lol.
