Okay so I've been playing this for a few hours now and here are my first thoughts;
Firstly the boosting prices are just too high, coupled with the cost of transforming the items into the next tier breaks the game if you ask me. The transformation prices as they are on their own would not be too bad however, but the boosting prices need to either be removed entirely or lowered drastically.
Secondly, while I am glad to see colour kits return, it makes no sense to have them differ in price. The prices of the colour kits should be the same. Red and White especially!
The sprites I'm happy to report are god-tier, I especially like the remixes of the ones before this update. Out of them I did see an error with one in particular, the legendary version of the Nightmare torso where part of the front panel seems to be transparent for some reason. I assume this error also appears on it's physical and electric equivalents as well but can't confirm.
