Its nice, could use an update or two though.
Just an idea for some things to add or update-
1. Rebirth(s) & Ascension(s)
2. Different upgrades (rebirth & ascention upgrades)
3. Challenges (ex. Reach <amount here> within <x amount of time>) or achievements (ex. Make <x amount>)
4. Sacrifices (ex. Sacrifice all your progress for one op thing) (sacrifice would be optional)
Just a few ideas.
