Very fun! Good choice of art, it doesn't distract from the mechanics of the game.
X/ (pronounced "ecks slash") is a simple, abstract game about attacking your enemies to move around.
It was made for the Game Maker's Toolkit Jam, with the theme of dual purpose design—in this case, attacking serves a dual purpose of also moving you forward, and likewise enemies are both enemies and things you need in order to move.
This should work on any browser (desktop or mobile). Tested and completely works on Firefox; mostly works on iPhone (sometimes taps don't seem to register, but that might be my screen?); Safari on my computer doesn't do full screen right and I don't know why and it might be a bug in Safari; not tested on Android or anything Microsoft since I don't have those. Or Chrome. I should download Chrome to test stuff.
I also put a copy on my website; I might update the website copy if I feel like it.
