Loved it! From the introduction it has the extremely delicious taste of an addictive cake. The puzzles are fun and the later levels that required me to restart, or just, you know, plain dying, were annoying in that kind of Super Mario Land-esque way where on little tap of the key meant you went flying into the abyss.
The graphics are wonderful aswell, very well in line with the jam, and I like that the game doesn't use shading, it makes the pieces pop really well, and while it could've made them just boring geometric shapes, it feels cozy.
Gameplay wise it didn't get tedious either, which is a feat in itself, since the mechanics are very child friendly. Opposite to what I just read someone say, I really feel that it would not have benefitted the game having to many different key bindings. Or even one more! Sometimes the physics caught me off guard, maybe they felt a little, how to put it... Too real? I think it would have been nice if the stars, or some of them, instead of tumbling down would've had a teeny tiny bit of float in them.
The only thing that didn't quite fit my tastes was the music, I would've preferred something more bit-tuney, and maybe a little more variation between the making of the constellations.
Summing it up: would love to have has an an endless starcatching game for my mobile!
