Now I normally don't like rougelike games, I like my progress to actual be progress, but this? This is a gem of a game that I now enjoy greatly and plan to continue more for those sweet, sweet recollection. The story/plot idea is great, the implementation is fantastic, even the hardness/RNG hits just the sweet spot - I was AGHAST at the very end of the second level/area and the sheer audacity of it. Already used all my stuff and BAM, reminder that someone's waiting for their skin and this time they're angry.
Will definitely be keeping an eye on this game, and I wish you all the luck on the full release and porting it to other places (this would be great on the Switch, I agree).
