It's basically a Hades clone with a Transistor-like attack system but worse in every aspect. Attacks are cards that you gather in the various arenas. Cards can be assigned to the face-buttons for their main effects or as buffs for other cards. This system is not bad (it works on the aforementioned Transistor) but the problem is that it's very unbalanced.

Some attacks are game-breaking from the start, like the punch that stuns-locks enemies, which you can also buff with a card that adds damage to stunned enemies. Others are complete crap, like a slow moving projectile that does very little damage and that you need to charge, which makes you a sitting duck. On top of that, you'd be a fool not to equip the dash card. And since you can rearrange your build freely at any time, even in the middle of a battle, there is no incentive of trying different builds. As a result even after less than 3 hours, all runs felt essentially the same.

Worse, if at the start of the run you get one of the crappy cards, there is no reason for you not to immediately restart the run. This is the antithesis of variety.

Each time you leave an area you get a reward and the option of buying permanent upgrades and temporary charms. But the upgrades are crap (why would I need the ability to sell cards? I'm never low on money and I need cards to attack!) and the available charms are always the same. So, again, you can always equip the best one and every run is the same.

What passes for music is a short 5-second loop and that not only is the voice acting terrible, but that the villain is CONSTANTLY talking, repeating the same dumb lines over and over again. The dude spouts some supposedly funny quip at the start of each mini encounter, at the end of each mini encounter, each time a monster drops a health item, each time you encounter a locked door and each time you find a chest with cards. I had to mute the game just to keep my sanity intact.

This is a good example of why you can't rely on brute random generation to create a compelling game, even if the assets and the gameplay itself are not bad in the abstract. You need to tweak things and think hard about player incentive, risk vs. reward and, most of all, balance.

The verdict is that the game lacks variety and while the primary gameplay is not terrible, the uninspired music and the horrible and too-frequent taunts make it a torture.
