Anything Helltaker gets my attention and this was a pretty fun and challenging game!
It was a little frustrating how picking the wrong choice in a conversation would send you back to the start of the game, but it only happens twice so it's not a big deal. Also I don't know if I'm the only one who thought this, but being restricted to grid movement while the final boss' projectiles aren't is a little annoying as it can be hard to dodge certain bullets.
But that being said, I really enjoyed the Hakkero mechanic, it really helped set this game apart from Helltaker, and added a new layer of planning and thinking. The cutscene art is pretty good too!
