This game really made me want to finish it, especially considering it has no save game option lol. I like how it combines the early 8-bit graphics style of CGA/ZX-Spectrum, but also the smoothness of physics based controls. I wonder how you coded the swinging. Also the "fog of war" is implemented really classy, in the 8 bit noise style as well. Controls feels good, also thanks to mid-air control. And man these leaps of faith I had to take letting go of the pick axe lol.
I think a full version with online scores would do nicely. Or maybe even a coop mode to torture each other with a friend lol.
