Nice concept! I tried out a few builds but had a difficult time getting past ~21 or so initially.
Maybe some things that could help are things like:
- Start launch timer to skip directly to launch? It helps in the beginning as accumulating currency is kinda slow
- Maybe a remove part button would be nice too, given I want to experiment with different ideas
I didn't end up getting to being able to buy parts, but was very curious what happens when you go over the max mass! I love these games where you see your build work / fall apart so definitely enjoyed it
