I mean, Since all you have to do is run around and dodge slimes, You didn't have to wield a sword. Those treasure chests was kind of unnecessary too, since they didn't give you anything
Would be great if the character actually uses the sword. Like a slashing state starts once he is facing a monster. And regardless of effect, a random item taken from the treasure chest will be activated immediately or with a time delay. Or it will auto-equip an equipment if that's what's there. This could give it more variation even with just one mouse click.
Given the time constraints of the game jam, 1 or 2 items would be enough, i think.
But yeah, concept for controls is cool. Just needed a little bit more variance and/or depth. Overall though, well done. :)
P.S.
It took some time for me to get that long press of the LMB would initiate a turning. Not sure if there was a tutorial somewhere. But if there was, i didn't notice it.
