Really addicting game.
The only thing i dislike is the fact focusing on one color seems like the best move.
Some feedback:
I think itd be nice to write the magnitude as an exponent besides the letters. Cuz honestly UVg means nothing to me. While 10^66 is pretty easy to understand.
Id like the option to disable the auto spawn from a certain color (this one mainly for performance issues). And while at it, remove it from the manual drop too, cuz i wanna be dropping my best colors not all of them most of the time.
I also would like a breakdown of current percentage of a color on my bronze per second. Under the highest value on color mouseover for example, if not an actual graphic i can check...
Performance fix ideas:
One I mentioned before was giving us the ability to toggle off the auto drops.
Another is after a certain number of balls are in play toggle off their collision with each other. One step further is pre calculating (storing) the path from the auto drops since they always drop from certain points. Two steps further is doing the same with manually dropped balls, cuz there are (for all purposes) finite points where balls are dropped and with no random collisions you can math out their path from launch.
Can even add a 'X balls dont collide anymore' buy. Or even a 'chance to ignore collisions (be a ghost ball aka phase through other balls) +0.05%'. So now it isnt a performance fix, it is a skill that itd be really good actually.
That is what i can remember right now, it is way over my bed time lol. Really good game, mate. Honestly kinda crazy how fun it actually is.
