This game was a huge surprise to me when I heard about it, and I was so disappointed that I missed it when it first came out, so when I saw it was available again I bought it instantly, and it beat all my expectations for it. Like other people have said, it's basically a porn version of Slay the Spire. You fight against enemies using a mana based card system, and over the course of each "run" you build up your deck using random spell drops with enemies, as well as other power-up artifacts in the style of games like Risk of Rain or Binding of Issac. The run continues until you either beat all the bosses, or lose a fight. While you don't keep your deck or items between runs you do earn experience to spend on talents to boost your stats and other things that make each successive run easier or different.
While the gameplay and animations are good, what really surprised me about the game was how much porn was already in it. Most of these kinds of games have a handful of enemies and one or two animations each, with a few cgs to go with them. Meanwhile Last Evil already has 60 unique animated scenes, with another 22 still image CGs. Nearly every enemy has at least two scenes, one for if you beat them and choose to drain their "essence", and one for if you lose to them. There's a fair amount of variations too, for example if you lost to a pair of goblins your game over scene is them DPing you, while if you defeated one of them before going down the scene will just be the remaining goblin having it's way with you. On top of the after-fight scenes there's an ability that lets you seduce enemies mid-fight, event scenes you can come across, and an NPC merchant you can sleep with to buy better spells from her.
There's a lot of nice QoL stuff too, like being able to customize your character to an extent (hair style/color, breast size, etc.), skipping seen animations, skipping foreplay animations, and having cum inflation enabled or disabled. While the game is early access, imo it already has far more content and effort put into it than a lot of the h-games you see on Steam nowadays. The fact that's it's technically early access is actually nice since you can expect even more scenes in the future; according to the dev there's a whole floor of the dungeon he's still working on, and since bosses, events and (most) enemies are unique to each floor, that means there will likely be a ton more content to come, though even with what's in it right now it's a great game.
The only major gripes I could imagine with it is if you didn't like the succubus design, didn't like the animation, or weren't a fan of the fetishes, since the majority of the scenes are either of the succubus having sex with "tempted" (i.e. defeated and/or mind-controlled) enemies or being raped by said enemies. As someone who enjoys that kind of stuff greatly though, I would 100% recommend playing this, and highly recommend buying it for real.
