Nice short incremental game. I like to see the rockets being assembled, then have the crew go in, count down and fly away. If you would want to extend this game, a possible suggestion could be to not have everything unlocked immediately. It is a bit overwhelming to have everything at once. Maybe have a different rocket that exists out of just "one part", uses "regolith" to lift off, and is "without crew". Then slowly introduce the different mechanics such as fuel, parts for the rocket and crew. Nevertheless, I really liked seeing the rockets launch, and played up to around 10000.
