Good game so far! I enjoy the mechanics. I've seen two issues though.
First, like others have said I lost the "infinity at" upgrade and 4 unspent infinity points when refreshing (Firefox 72.0 if that matters). Something is not saving correctly.
Second, I think the multipliers at the top might have a problem, or if not I am misunderstanding them. When my red gets to 1000, the speed is listed as 2.44M/s (I have speed bonus x2). To me this means that the multiplier should be added to 2.44 million times every second. Even with a multiplier gain of 1, wouldn't that mean the red multiplier would get 2.44e6 added to it every second? Mine is at 63e3 and climbing slowly.
Possible bug: I just stopped accumulating DM, but my RP continues to grow. DM is at 102,550,272. Not sure what other numbers matter for you to try to reproduce.
