Pretty fun!! Nice work. I had a good time upgrading XP to like level 250, then going nuts on attack speed and move speed until player 2 was teleporting around. I didn't understand what the upgrades did besides the magnet. The "5" in the font is weird looking haha. Overall good presentation, the skeletons are cute. I like the wavy background on the upgrade screen. The sound fx when you click a button is satisfying.
Well done!!
