Hey, it's CookieJar from the GMTK discord. Honestly, a very cozy and cute game. I love the interstitial rocket flying segments: navigating between comets, sometimes threading the needle between a small gap, other times flying way off course the destination and ending up somewhere completely random... I've flown out into oblivion no less than once from missing my target planet, and I feel all the more joyous because of it. The rocket flying mechanics are surprisingly so finely tuned, bravo.
For this reason, the planetary segments are kind of just okay in comparison. All players really need to do there is make one loop around the planet, collect especially the green rocks to re-fuel, and move on. And with the countdown urging players to get on quick, it feels like the game's crux is actually in its flying segment, as if the resource collection of it all is but afterthought. I will say, though, that the astronaut sprite is pretty adorable.
With all that said and done, this is quite a fine game you have here. Expand on the in-planet systems and mechanics more and you might have something special. Good job, congrats on participating, and I wish you all the best.
