This was a complete blast to play! I'm looking forward to getting all of the achievements, but some of them seem in my opinion a bit too extreme, like "The Blade Overlord", "Adrenaline God" and "Master". I know that this game is meant to be hardcore and a real challenge, but for some of those who really love hunting achievements ( like me ), this is an unbreakable barrier. I would suggest to maybe lower the ammount needed just a little bit, or maybe just change the achievements that follow that pattern a bit.
Anyways, I really enjoyed it! The combat system is really fun and epic, getting the medals feels satysfying and the different skins are also really neat and colorful. Maybe more skins with different costumes, not just colors? ;)
Good job on this! Keep uptading this game, it's very entertaining and definitely has a lot of potentioal ;3
