is there any tut on how to use cheat engine for this game? I cant seem to figure out how it works
There isn't, and based on previous responses it seems like there won't be one. It'd likely be outdated with the next update anyway, and the current game can be finished in about half an hour or so. If you have mechanical issues, you can basically just stock up on potions ad infinitum anyways , you just need to put in a little bit more grinding on basic mobs. If you think you need cheat engine, you haven't played more than 2-3 min or you have never learned the controls.
Cheating is currently harder than playing the game normally.
I can understand that maybe you want to do it for other reasons, but in that case I'd strongly suggest learning how to use ce with a game that doesn't receive constant updates, otherwise you have start over again quite often.
The small mushrooms (not the boss) will keep respawning so you can get money to buy mushroom soup.
The first mushroom boss also has attacks that can be dodged rather easily if you step back a few seconds. Don't spam attack, you will be locked into the attack unable to dodge. If you still make mistakes, use the mushroom soup to heal.
