It would be nice to have some more space on the sides, and maybe a fullscreen button too.
Other than that, though, the polish is perfect, and the mechanic is excellent. I will be addicted to this for a while.
Thanks a lot for playing, and for the feedback! I tried adding itch.io's fullscreen button, and although it worked fine, I think people playing in the default size could end up misclicking this button while playing. Still, I'll look for a way to add a fullscreen without using onscreen buttons after the jam is over.
I'll also look into making the walls on the sides a little bigger. Thanks again for the feedback!
I found a game that doesn't use that for fullscreen. I thought you might want to see. https://simonknowsstuff.itch.io/the-sword
