Melee wizard? That's odd :) I was thinking I'd have range attacks so I was a little bit surprised. The game looks really nice and after some polishing beyond the time scope of the game jam it could be really fun to play :) I didn't have any issues with moving around the map and some part with the issues with fighting were skill issues, I believe :D
Since you apparently really like issues (that's not healthy to eat so many in 72h, you know? but I'm not your doctor :D) so here have another one for using Godot:

that's correct actually, it's an "instant" attack like in Risk of Rain! So there's nothing that spawns and moves, just a raycast that shoots across the screen, then the sparks just spawn exactly where it was hit. You may want to play it full screen to see it. I'm not sure how many other games do it like that, so maybe people aren't too familiar with the mechanic.
