This game really is a shock to me, seeing the ascii map and the mechanics done so faithfully (or at least faithful to my half remembered memories) was a pleasant surprise. The visuals and aesthetic are fantastic. I really like how the Cum mechanic works in general, it's a cool take on a "sanity" system and the game's difficulty is pretty great for the sense of it being hard initially then becoming easy as you understand it. It is genuinely fun just as a game.
The only real feedback I would give is that the cum system, while balanced, can be a little tedious. Maybe add a few ways to shed cum at a faster rate, like a "mega fap" spell that costs 100 mana and drops 100. Using the mana rings instead of the regeneration ring feels balanced, except you have to pick carefully when to fuck, chain heal and chain pump out cum, which is a lot of clicking to the same effectiveness. Also maybe add some % based stuff, like perhaps the orb could reduce cum by half unlike the pumpkin's static amount? Lastly, maybe rework cum rings to reduce the amount of cum she takes on, but maybe that's in newer versions.
I ran this on an AMD card that had to use dx12 - my drivers are bad - but I experienced only two crashes. One while finishing the game and one while exposing the hidden walls. Pretty damn stable. There is a bug where, of all the settings, it won't save the capped framerate setting, though again maybe you've fixed already.
