I guess top five game in this jam. I know your game in LD43. I play once before. Maybe several weeks ago. In terms of this game, I made one shooting game as well and I surprised you can make shooting game so fun and close to the theme. I guess the most difficult point in this game is the physics system(gravity and drag to another planets).
Also Your guild(tutorial) designs so well although many words, you seperate them and makes players easy to read. Nice graphics but best audio. high rate now.
