Thank you! Glad you appreciate our game :)
Yes, you're definitively right about the arrow keys! We aimed for a mouse only game, but finally this was not such a good idea... That is why we added the spacebar focus ability at the very last moment, and I think it already helps a lot.
I give you a hint for level 2 : use the 3 asteroids coming from the bottom as a starship for the blobs. Be carefull not to slow them down too much when connected with the starting planet.
We agree that our levels should have been a bit more intuitive, and we wish to rework that for a post-jam version of the game.
