Got it going on Win10. Nice spare 80's look, very responsive. Still not quite sure how macro can be used strategically, but did use it (mainly to climb stairs). Seemed to have a problem with the skeleton enemy -- if I touched him it started over. If I hit him, start over. If I try to jump over him... walk around him... Start over! ; - ) Amusing to see a game like this using "hyrule" (as in the Zelda games).

Glad you managed to get it running on Windows, that's not a platform I could test with.
To pass the skeleton you can jump, then hit the macro button mid-jump and move forward over it. There are other ways, feel free to experiment :-).
The player attack move has not been implemented, which is why you're unable to defeat the enemy...
