Hello! Congrats on a trillion! That is one of the current "milestones" of the game, although the main way to beat it is to gain all the upgrades.
You're right on the three areas; they are planned but haven't been implemented yet. A prestige system, multiple areas, achievements, and much more are coming in the future (it will take me a little, but be excited).
Right now, my main focus is on fixing current bugs like the performance issues and the ball pinning right now so it won't slow down dramatically.
Thanks for playing my game a ton and leaving lots of feedback! Be excited for what's to come!
