Translation is fine, though I found it funny intends was spelled at itends:
Game feel isn't missing anything. The abrupt music restarting is a little annoying, but I assume it's temporary.
While I enjoyed myself, it's way too hard for someone like me(only able to do at best a 5 combo, where several orbs need 8+ to do 2x damage). I could do a couple of normal encounters, but the green and the boss blew me away. At any rate, the design seems pretty solid, with varying relics and orb effects to change how one plays.
Overall, well made if difficult game. May come back to it to try and beat it.
