Wow very impressive for your first game jam!
I really like the art and monster/character design. Also you manage to give each monster a different ability which feels great when I encounter new enemies
Personally I find the character moves really slow, not in combat but outside. It feels like there is more walking then fighting. Placing enemies closer together can also solve this problem.
I also felt that the attack has no impact behind it. There are many ways to improve this:
- Screenshake on hit
- Anticipation frame
- Bigger arc when swing the weapon
to name a few.
But still fun little game :)
