Initial comments:

- Maybe a more explicit "Reset this infinity" button rather than having the big crunch button double as that.

- Clearer indication that removing the first infinity upgrade disables you from getting other upgrades as well.

- Preventing people from buying any more dimensions once they've reached 1 might be a good idea in some cases.

Other than that so far so good, I love the concept of having essentially infinite resources to buy things but allowing for, basically, negative of a currency.

Update: Had some good fun with this but it dwindled out at the end where it eventually got very very idle. Was nice fun figuring out the correct combinations although slightly overwhelming. Overall not a bad game, if the upgrades were very slightly less generic that would probably make it better, they're already a lot nicer than a straight boost though. Some of the upgrades have nerfs which are far too great making them not worth it.
