This is an extremely cool game idea mate!
Struggling with the level 7, level 5 can be completed without any commands, not sure if that's intentional?
sry for kinda late response. yeah, as far as i remember level 5 was made to introduce you to the no signal tiles so you didnt need any commands for that.
level 7 is the main level for the no-signal-tiles. the whole game is suppose to be you remote controlling a robot, and therefore some times the signal is bad and you can't see what is at a certain tile. thats basically the black no-signal-tiles. and in level 7, since you cant see whats there you gotta guess your way through.
thanks, for commenting. always appreciate it.
