Surprised nobody commented on this game yet, it's a really good, polished work.
I played it all the way till the end and it was fun and not too challenging but not too easy, well balanced.
The final boss felt a bit annoying because it felt like there was like 1 frame to dodge but aside from that I have nothing to complain about.
Music is good, vfx, art is good, story is good.
Never played Helltaker myself but seen gameplay and reminded me of that game.
Good job :)
