A blast to play! The vibes are immaculate and I appreciate the flexibility you gave players in choosing their upgrade paths. The risk-reward tension for being greedy later on was really satisfying. I think my only real constructive feedback would be to tweak the upgrades numbers/prices a bit; having some higher-yield options that cost maybe 1,000-2,000 would break up the economy pacing a bit, so players don't race to all upgrades early and then have only a single goal left for a chunk of the playtime. Really well done overall!
