I've played this game for last 4 months of its Early Access. It already looked very promising and awesome. With the release it took me only a few hours of playtime to confirm everything I was ready to write about.
This is a rogue-like rhythm dungeon crawler, as you've probably read on the store page. The genre is quite unique - its gameplay is a blend of turn-based combat but it's constrained by the boundaries of the "beats" of the music of the level (unlike a lot of rhythm games it's very forgiving on beat accuracy and there's a reason for that: it's quite action-packed, so when you have a few skeletons, fiery dogs and a dragon converging on you - you can't really follow the beats within 20% margin what is usual for rhythm games).
First things first: this is a rhythm game and its soundtrack wirtten by Danny Baranowsky is just pure essence of awesomeness. Randomly generated levels are extremely well done. When I say extremely I mean it. This game doesn't have unbeatable generations. It may be easier of harder, but it's a fair rogue-like, if you die - it's your fault. It's not like rogue's tale when you can be killed on first turn the moment you spawn. So you won't really be stomped by something you can't beat.
With the release the game has been augmented with some kind of plot which makes it a bit more beautiful than a rogue-like w/o a plot. Also this game even during Early Access didn't have any gamebreaking bugs. In 80h I never had a single crash or anything else that'd ruin my gaming experience, since technically this is kind of a day1 for thi game - it's exremely polished, which is a good example what Early Access system should be used for and how.
With cutscenes you are being rewarded with when you complete "zones" with different characters, with easier and harder characters themselves, with a big variety of items, leaderboards, daily challenges - delivering beatdowns to the beat in this game is guaranteed to be one your best rogue-like experiences ever.
