Nice! I like the idea here a lot but a few things could have been more clear. I wish there was better feedback to let me know if my solar panel was the correct angle. Also I ended up losing my batteries and having to wait for the entire night cycle to circle around. I with it would have fast-forwarded to the next day cycle but cost me some points or something. Also, after recovering from losing my battery, I ended up moving directly into a shadow cast by the leg of the spacecraft and was instantly out of batteries during the daytime. That aside, very good idea and a lot of fun!

How funny first I wanted to make my entrie simliar to this because when I heard the gamejam theme I immediately thought about poor Philae dying on this asteroid xD

Nice game. 

Only Night cycle was bit fast and rotating solar panel is hard for me too

I always liked space games. Day night and solar panel was a good idea. Rotating solar panel was a little hard for me. There's not much to say about the game. Detecting light was a bit hard but two lightning sign helps a lot. I entered Night shadow by mistake and I couldn't escape Night cycle. it's quite simple but fun.
