Thank you for playing it all the way through, and for the detailed notes! 3:30 is right about where I hoped people would land.
- The keepsakes aren't actually random. Each one is tied to a container. But their bonuses had nothing to do with when they show up, which is why the order felt so unhelpful. I've reworked them so each one helps whatever you're using at that point in the game. I like your idea of fewer but stronger keepsakes, with about 3 active at a time that you can swap. That's a bigger change, so I'm going to think about it rather than rush it in.
- You're right about the late game. The keepsakes that come out near the end now speed up your cousin, which helps a bit, but it doesn't fully fix the cousin not keeping up with the belt. Running out of upgrades with 100k left is the bigger problem, and it's next on my list.
- Not just you, I think. The conveyor can arrive before the lane upgrades feel finished, and then they stop mattering. I'll look at it alongside the late-game pacing.
The keepsake changes will be in the next update. Thanks again, this was really useful!
