Great game! I love the space theme. The progression system really makes it feel like you are building an actual space program, and the music fits that vibe perfectly! It makes you feel like you're living through the history of aerospace transportation, you try, you fail, you fail again, and then eventually, you step on the moon! The core mechanic is super interesting, too. Sure, the card-matching concept isn't entirely new, but I can't lie, it's incredibly fun and satisfying to search for those matching pairs! Great job!
By the way, if you have some free time, I'd love for you to playtest my game as well and let me know what you think!
