Great look, I really like the low-framerate animation look for the robot and some of the vfx - it's pretty surprising how well it works with sci-fi mechs :D
Zipping around on the grappling hook felt really good and the dash was nice. Jormangund was my favorite because of the sound design on it -- those deep bass hits really gave it a feeling of scale and gravitas and dodging the huge laser beams was really fun. The sound design was quite good throughout, though I did feel like some of the music themes were a little too happy sounding for the boss fight setting and the breakcore loop did get a bit old. Overall a great job though, super impressive you were able to get this all done solo :)
