This is the first Game Jam game I played this year, and I have to say, as 'simple' as the concept is, it was a very enjoyable experience. There was no need for lots of introductory text or explanations - the gameplay was very intuitive and the pacing was great. There was parts where I thought I was stuck but then kind of naturally figured it out. I especially found the hand prints that display on the blocks a nice touch. The atmosphere was very chill and spacey thanks to the music and sparce use of sound effects (only from moving blocks or teleporting). The textures were nice, as was the use of image backgrounds. While the gameplay was a lot simpler than Glitch, I actually didn't lose my patience with this and managed to clear the whole thing.
There wasn't much content to the game, but in its defence, everything that was there was very nicely polished. The rooms were interestingly arranged and the atmosphere really worked with the theme. Some of the textures could use a tiny bit of fine tuning perhaps (I found the textures at the crash site/opening kind of jarring and unharmonous, maybe they clash with each other or the background), but the space station areas looked great.
I'd like to see more of Klots and would definitely hop back in to play more levels.
