Simplicity and variety of levels convinced me this is a good addition to the Game Jam of this year. Its gameplay is rewarding and well adapted to the interstellar space theme, while always being unforgiving to most errors. The atmosphere is relaxing, but I feel pushed forward by being allowed to see the levels ahead.
In level 5, when the structure nodes are introduced, a section is misleading you into thinking you'll be safe, leading you to the void instead, but I guess it's fine. The concept and textures might be considered basic by some, however I think it doesn't hurt the experience much. I didn't really find anything else to report on the negative side. :)
A great zen puzzle game to lose yourself into for a while, I can recommend it.
