I actually think that the changes to the thrill levels, particularly the upgrades of the buildings, makes a lot of sense to me. I mean - I also dropped levels, but at least I can get some credit for upgrading Mickey and Friend collection buildings in the initial zone (which you didn't before).
I also like that you don't need common tokens to upgrade buildings. I mean this will save me from waiting for the Fun Wheel to drop like 1200 balloon tokens before the Mickey common token is removed from the chests. I'm pretty happy about this.
Now, the reduction of magic from buildings that aren't upgraded - NOT happy about this. But I suppose, with the good comes the bad.
