This game is pretty bad, even for a roguelike
If you want random chance then have a random chance for abilities to proc or have randomly generated loot, making the mushrooms on the ground randomly perma raise or lower your stats is insane because the optimal mode of play is just to not pick them up at at all and just rely on the natural stat gain from raising your level.
It's ridiculous to build conflicting ideas into your game and then shrug your shoulders and say "Eh, that's how luck works!"
The art, I can understand. Not being able to have screen presses path your character to the point you click, that's a programming issue, sure, I'm sure you'll figure it out.
I just don't understand why you'd cripple your own game with measures made to frustrate you.
