I's been a while since I've played the game SO satisfying to play. The soundtrack is AMAZING (although there's the same song for each boss - would be better with more variability; the bosses also look almost the same, albeit each of them have a bit different abilities). Weapons are well designed, but there could be more than just 2 basic + 4 optional. The difficulty is decent (I'm playing "Goat"/medium so far) and new enemy types are being introduced in good order (some of them are just buffed up versions of the lesser ones, but they are buffed up good). The number and rising difficulty of challenges for each Hell level is alright. The levels are well designed - I don't feel like walking at the same area over and over again. The story is quite interesting, I feel for the Unknown's fate and I like the idea of having a (very well voiced) narrator, leading me through the plot. The game could be a little bit longer, but I understand it's not easy to find so many cool vocalists wanting to cooperate. I hope there will be a second part, once this one gets popular enough! The only bug I encountered was when one enemy blocked behind the wall and I couldn't kill it, so I had to restart the level (fortunately it was right after the start).

Gameplay: 8/10 (similar boss fight tactic; could be a little bit longer; rhythmic combat system is 10/10, though)
Audio: 9.5/10 (repetitive boss theme)
Video: 8/10 (repetitive boss looks)
Overall: 9/10, waiting for DLCs / M:HS 2!

Edit: Okay, so apparently some of the boss songs are similar, but different, which I didn't notice in the heat of the fight. The final fight was different than previous ones, but not that much challenging. Getting 100% achievements was fun though, especially trying to get that 100% of the beat without exploiting loop holes. I kinda wish there were more achievements, e.g. involving difficulty levels, as all of the current ones you can get without even changing the difficulty.

PS. Congratulations for getting the Golden joystick Award, well deserved! Now here's to getting the Steam Award in "Best audio" as well!
