Thank you for this game! The combat system was really well done. Good animations, and it felt nice to 1-shot those purple dudes.
A few suggestions: Maybe add in a stat description. I made assumptions on "Move" being similar to the speed potions (just permanent), but I wasn't positive. Also, a smaller area would make the speed potions less needy, and you could focus the items on other cool stuff (damage over time, area effects, etc. could be cool).
Definitely a good base, I hope you keep going and expand on it! Make some other enemies with ranged attacks, or bossfights!
