Hey, that's a good game. I enjoyed it :)
Just a few quick notes:
- the "premium time remaining" doesn't always show 2 minute digits (e.g. 2:5 instead of 2:05)
- the "progress" tab will remember the previous run's state if you don't pick a level (with the restart button still working)
- at higher multipliers, the news bar cannot keep up with my gameplay and will show items for a long time to catch up
- not sure when I did this but at 16e12 total gold I noticed an extra achievement (11 from 10)
- the 2000x multiplier cap isn't that hard to reach and isn't documented anywhere
