I would LOVE to see this updated, the idea is great and the loop really got me hooked! I can imagine sinking a lot of time into it. I didn't do well because I'm a little wet behind the ears. The requirement ramp is way too much/the upgrade path too strict. I played 10 times before it was smooth sailing.
- Some other issues:
You can try to click to collect right as time goes out and accidentally buy an upgrade - Click to collect was finicky sometimes, I had to click a couple times
- Upgrade count could show "-1 left"
Despite the issues, I had way too much fun on this one, nice work!
