First of all, thank you very much for the comment and suggestions!
Regarding the difficulty, aren't you in luck?! New version with Difficulty modulation just went up!
Saving runs will definitely be coming, a lot of people have been asking for this feature, so I'll make sure to add it soon enough.
The current graphics settings are virtually useless, and a proper "high performance" mode is something I want to tackle but have been putting aside in order to focus on more flashy features. Still, I will have to work on it at some point because the current PC required to play this is definitely not in line with how the game looks.
At some point I'll add in patch notes, they aren't in place at the moment because up until last week my player base was basically 0, so there was no point in having them. Even if it's just 4 people instead of 0, now I don't have that excuse anymore, so I'll have to add them soon enough.
I'll keep doing minor updates whenever I find and fix more gameplay bugs, but the next big thing coming is the achievement/quest system that should give the roguelite gameplay loop a much more rewarding zing to it.
At any rate, thanks again for your feedback, and do let me know if you find any bugs!
