Thanks to some amazing feedback, I've updated the UI to be a little clearer when you're dragging around your fuel items to the engine. The engine will now highlight the segment or ring that's affected by your current item, and items that will either be affected by your held item, or will affect your held item, will be highlighted in the engine.
Previously:

Now:

- You can now successfully FAIL in endless mode. I left boosts unlimited in the original demo, but it led to some players feeling as if they were missing something by never being challenged.
- I've added a little reminder to check out the engine manual for new players. If you've already played the demo, this probably won't appear - but do read the manual anyway!
- Items in the stock will now not count as triggered when they have effects that trigger after x boosts.
- Stopped items flying off occasionally when dropped in strange places.
