I spent ages trying to figure out level 3, I thought I was just not getting something, until I saw the explanation in the description. I really tried hard to understand it, but the arrows dont make much sense to me. Other than that, this game is good. It has nice potentials with the puzzle especially when you also factor in the recharge station.
I must say that robot did move kind of slow, I know this was intended but to me the game would have benefited from a slight tweak to the speed, I feel even for a slow robot it was just a tad too slow for my personal taste. Also my instinct was to dash downwards to the portal at each level, but I kept failing even though I went right into the portal and had to restart level 1 and 2, not sure what is going on there. I really wish there would be more to critique, and I would have gladly played some more levels when I was at it.
