Thoroughly enjoyed this one.
Loved the red/black colour palette. Everything from the character, their chainsword, the enemies and environments had an edgy apocalyptic look and atmosphere that I just really dug! And a weird thing to single out but I really loved the drill elevator.
The checkpoints were generously placed, as to make things challenging but not too frustrating. The Bosses lacked a little fanfare on defeat, but you can only do so much in the Jam timeframe.
My only criticism is sometimes I had issues with lower visibility, for like landing on platforms and stuff. And I think I accidentally skipped a hint at the beginning because it appeared just as I was in attacking range of an enemy and instantly clicked it away. Didn't hinder me though.
And a suggestion, it'd be cool if you actually had to stand on those women's dresses to attack them between their attacks. Putting them on narrower platforms was good, but most of the time I could be in striking distance and keep attacking while they couldn't reach me.
Oh, and how did I nearly forget to mention the intro. I actually restarted the game because I thought something had gone wrong at first. That pull-out was a terrifically impactful moment!
I've got a record I'll post when I upload it.
