Cool little game, made it to the end easily enough. However I struggled initially until I worked out you could wall climb, I don't know if others had the same issue or if it was just me being stupid lol. Anyways it might need to be a bit more obvious that you can wall climb.
The only other criticism I have is that the movement is a little jarring, I understand it may have been an intentional design, moving from pixel to pixel, but unfortunately it didn't really work for me.
apart from that I enjoyed the game concept. I especially liked little details like that the battery was the same shape as the battery holder, making it obvious where you had to put it. The game was relatively easy to follow despite the restriction of the low pixel count. I can imagine this is hard to pull off.
Thanks for uploading the game,
