Wow! First off, this game has TON of content! I'm really impressed with how much you got done in the jam period. The graphics are great, I really really love the little animations when you sit on the couch, eat, etc. The setting has a cool atmosphere that all feels tied together!
Collecting upgrades is always nice, though I didn't feel much stronger even after 3 horns were collected.
I only have a few nitpicks... the platforming felt a little off. I would constantly miss jumps or have trouble getting up ledges. I'd also get stuck on little lips of ground occasionally... a minor annoyance sometimes, but death if you are being chased! My last nitpick is just me, but I found it quite hard! I know it's Darksouls inspired, but having never played those I don't have a huge frame of reference. I found the red knight enemies harder than the first full boss bounty!
All and all, this is a really amazing game! I still have a lot of other entries to play, but I imagine this will be among the best. Awesome work!!
