If you like Roguelites, this one does it well. It'll keep you entertained for a good 100 hours or so to unlock everything, more if you want to pursue greater challenges in the Limbo modes that unlock after beating the game once in Nightmare mode.
Every achievement unlocks something cool in the game: new characters, active skills, passive skills, game modes, run modifiers, etc. It's a great way to do meta progression, since you can unlock things in any order you want. It keeps you strategizing and working towards new builds each run, preventing things from getting monotonous.
You have a lot of granular control over the difficulty with the Lucid Dreams modifiers, but those are unlocked through achievements as well, so if you want to tone the game down beyond the default lowest difficulty, you need to earn it.
Balance swings wildly between seemingly impossible and trivial, but you quickly learn that depends on how solid your build is for that run. Once you figure out what the terminology means and how all the different parts of skills interact and scale, you end up bullying the game.
Twitch skills are necessary to avoid boss mechanics and stronger trash mobs, but some characters are pretty sluggish in terms of run speed and dodge cooldowns, which makes certain bosses' attacks impossible to avoid by default. You'll need to find skills and stat upgrades mid-run that give you mobility or allow you to tank a few hits. This isn't balanced like a Fromsoft game where you can beat the game without leveling up if you're patient enough. You kind of need to brute force certain mechanics through damage mitigation, healing through it, or just exploding the boss before it gets the chance to eat you alive.
The characters all feel pretty different from each other, and they all have a lot of customization options. There's a decent amount of active skills and passive skills, and they interact with each other and each character's unique passives in pretty interesting ways. The terminology is a bit confusing, and the game doesn't do a great job explaining it, but if you like theorycrafting and planning out broken builds, you won't be disappointed.
I get the feeling that some of the character designs were either someone's fursona or OC, but they're bizarre enough to be interesting at least.
All in all, it's a solid twinstick roguelite whether you're playing solo or with a buddy. Highly recommended.
