Overall great job, especially for a team of two! I really like the art/animation style and I think you've got a solid gameplay foundation here. From a sound design perspective I would say there could be a few improvements:
- sound effects overall could be a little louder, it's difficult to hear them over the music, so lowering the music volume or adding a volume slider for music and/or SFX would be nice
- having the following sound effects(or making them louder/more audible if they're in the game) in this order of priority would IMO help make the game feel better to play and more polished: a cue for the attack charging up/finished charging, enemy attacks, enemy movement/agro(vocalization), teleport charging and ready sounds. weapon switching sounds, ambient sounds.
this could be a solid start for a project outside of a jam, well done.
