to start, personally for me Performance was fine. not to say others didn't have different experiences, but i haven't had any Performance complaints. you've been here before, you know the drill. go through floors of Dungeons, enter Rooms, Kill those Enemies, move to new rooms. explore for more Enemies (Character Levels/XP), or sometimes loot/XP/secrets to pick up. take on the Boss of the Dungeon floor when you're ready, to move to the next floor. every Class starts with a basic Wand (there are like more than a dozen Classes so i'll admit i don't know if any of the Classes might actually start with more than just a Wand, as the Classes are unlocked and the unlocked ones seem to have larger differences than the basic ones do), and you'll pickup Weapons for 3 Slots that you have for additional Weapons. each Slot is dedicate to a specific type of "Ammo/Mana", so you can carry one of each type in total. if you find something new you can swap out ofcourse. Character Levels (or things you find) as you play each run, will determine what upgrades you get other than just Weapons. can vary from increasing passive Stats to conditional actions. overall, the variety of Weapons, Character upgrades, and Enemies - is decent. you're not going to see new Weapons/upgrades/Enemies for hundreds of hours, but there's enough variety to give you some choices and to have different Enemy compositions as you go through the floors. IMO, the replay value drops a fair bit once you finally beat the game on any Class (not infinite floors, there is an end), but if you liked the game a ton then i could see still playing it from time to time. which i had done myself, i'll launch it again once in a while and play a run. enjoyable enough to launch once in a while and play, and then put it down to prevent burning out on the limited variety. if you like these types of games, yeah i think you'll probably like it. as long as you're expecting a decent game rather than a revolutionary one.
i actually really wanted to like this game. it seems interesting from Screenshots and Trailers and such. however the Enemies are so-so, but most importantly, is that the Weapon Parts you go through, are just largely uninteresting. and by this i mean that most of the Weapon Parts just don't feel good to use or feel like there is little difference with or without. or, quite a few Parts just felt like downgrades to even have, without a relevant upside to them. you can unlock more Parts and maybe those are more interesting but.... i'm not going to grind through a game for dozens of hours or more to 'unlock the fun'. if it doesn't feel interesting to start off with, hard to convince the Player to go the extra mile. Boss #2 (since they go in order as far as i could tell) was legitimately cool, though. though Boss #1 just felt tedious and like nothing was happening for most of the encounter. also Mouse Input always feels a little bit weird in this game. the Audio mix is almost painful and forces me to turn the game down very low so that i can ignore most of the Audio. one may be surprised at how GPU intensive the game seems to be for what it is.
