So I'm just gonna try and erase this game from my memory because I'm finding absolutely zero ways to reliably deal with some of the shit this game throws at you.
Catzilla has to be the worst boss I've ever faced in any game I've ever played. The wandering/random bosses (sometimes) annihilate you unless you're prepared specifically for them, The Hunter was the only one I found actually manageable. And the most recent one I encountered, The Factory, seems like it matches Catzilla in it's bullshittery.
If you grind early game enemies for money and xp, Catzilla comes up when you hit level 50 and takes HALF of whatever you gave to Hizi if it wins (It WILL win and you WILL lose 300K+ xp). So you try to keep yourself below level 50 until you have enough items and throw whatever xp puts you over level 50 into Hizi, but surprise! The Factory (which IS an optional fight) levels itself up to MATCH Hizi's level... Cause why not... And the items are completely random and require absurd amounts of grinding in order to choose what rarity you get. 95% of the common items are either jokes or completely worthless, the rare items kind of help, and the legendary items are actually game changing but good luck getting them if you have real shitty luck.
If I EVER come back (highly unlikely), it'll be because I grabbed the cheat codes from the discord and only wanted to see what they did. As well as what the rest of the game is like. I originally wanted to play it legitimately this time around but... just read the like 10 comments I posted recently on this game and you'll find out why I'm actually giving up on this game.
TLDR for those comments: Balancing's pretty bad. Difficulty spike is vertical and NEVER stops going up. The enemies get more resources and tools than you EVER do. Dev's response was basically him completely ignoring all talks about difficulty with what is basically a "git gud" Lord Farquad meme.
Edit: Replaced/removed unnecessary swears. I'll admit, this was uncharacteristic of me. Yet what I said still holds true. What I said were still valid criticisms, they were just hidden underneath a small cloud of rage from me writing them immediately after playing the game and getting screwed over by it. And I will not be taking them back. If you enjoy this game, then good for you. But I genuinely do not and every response I've gotten has been ignoring that fact. The fact that I find everything that this game does to you, a detriment to the player's enjoyment. That is all.
