Like others have mentioned, the movement speed is really brutal and, in my case, disincentivized exploration unfortunately. I also don't know it was a functional choice (e.g., easier/faster for you to implement) or a purposeful design choice to bind weapons to mouse, but I would have loved the option to swing my sword with a keyboard key as well so my laptop would be more useable (mimicking more a Zelda feel). Finally, would love any interaction feedback in the environment. Monsters flash when you hit them, doors highlight when you can interact, etc.
Nice job on building a little dungeon crawler - that works!! With all original art! That's huge, I hope you feel building.
