Wonderful game that feels very complete. Though the monsters behave very similarly, there is a large variety of them, keeping me hooked throughout. The difficulty is also perfect for a game jam, with frequent level ups. The cool final boss seals up the game nicely. Having a working setting menu is just another sign of polish.
Other than the odd screen size, one tiny pain point would be the inability to cancel my attack once it is selected. If I am to nitpick, player movement can be made smoother when holding down a directional key.
Still a very well made game. Great job!
