Cute lolis with swords and magic, a story that's heartwarming and light, yet engaging and a difficulty that reminds me of the classic JRPGs and like. While I do agree the controls _could_ be a bit better, they're far from unusable. They're also not that bad once you get to them. The strange movement inertia on anything you do is annoying at first, but once you get the hang of it you can compensate your timings accordingly. I see a lot of people complain the game is impossibly difficult but I'm on my first playthrough on hard and while it's certainly challening, it's definitely nothing new to people who are familiar with "difficult" games like Ys and the like.
As mentioned in some other reviews, buttom mashing is a one way ticket to an endless loop of dying. Learn your combos and figure out what works on what enemies. What you can use on a slime won't work on a mothbee. What works on a mothbee most certainly won't work on a Cocorat. What works on a Cocorat won't work on a Merkid Mage. Each character you use will obviously require different tactics to use and with each character, your combos and tactic will again change depending on which enemy. It's a challenging game in that you need to be able to quickly execute, chain and modify your tactics as you go because rarely will you ever be fighting just one type of monster at a time.
The game itself is immensely adorable and the localization by Carpe Fulgur is absolutely fantastic. If you're like me, you'll come to love the characters very quickly. (And also feel terrible when you accidentally die. Whoops) The art is definitely a double thumbs up and the variety of character portraits for dialogue really add to the atmosphere and feeling of the game.
One thing I also want to highly praise is the music. I know it's not an international award winning soundtrack or anything, but the cutesy, lighthearted music is really enjoyable.
Overall, just be prepared for a steep learning curve that'll be mercilessly brutal, but once you get the hang of it and you get the ball rolling, oh boy oh boy is this an enjoyable game. Arche's adorable.
