Well, in the end it was better than I thought it would be. Completed what feels like half of the game atm.
The combat is pretty simple once you understand the basics. Even when enemy has 4-6 times more HP than you, it's not really that hard to win unless you get really unlucky with card drops. It's probably one of the easiest card games I've played, or I was really lucky ALL THE TIME (which is possible but unlikely).
There are upgrades sold in the shop and you can buy the cards that you need (also you get them as a reward sometimes), so I really haven't felt like the game was unfair. Had to replay one or two fights for a few times, but it's not something that was hard or annoying to do, fights are pretty quick because you basically just spam attack cards and then defense cards when the enemy attacks you, or both at the same time. The important thing is that you see what enemy's gonna do in the next move, so you're basically limited only by rng.
Once I got my hands on good cards and got enough upgrades, the game became even easier, I haven't seen a single game-over CG yet somehow, looks like I've lost only to enemies that didn't have any game-over CGs or they were something like an optional mini-boss, idk.
The music in this game is great, I really enjoyed it.
The CGs (at least the few that I've seen, the ones that were shown in the events since I haven't lost a single time yet) are pretty good but nothing special, a simple live 2d. The voice acting really adds to the experience here and without it these CGs would be very boring, but it's loud AF, had to lower it to like 20% in the settings.
I think this game is a solid 3/5, would recommend to at least try. There are better card games out there and this one just feels mid compared to them, but I wouldn't say it's terrible. Maybe I'll change my mind in the future, but as of now, I think it's good enough to at least complete it once
