Thanks for playing and the feedback! Always fun to sneak in a bit of education to unsuspecting gamers ;)
I actually did have a pyramid like grid for the possible positions earlier on in the (whole 2 day) development cycle but decided to leave it out because of the mechanic introduced in the last few levels (which even didn't end up being that great). So I played the game mostly with the grid on myself and then when I disabled it, I had gotten so used to the positions that I didn't notice the necessity of it. Will definitely put it back in if I decide to do some kind of post-jam version of the game.
