Oh hey, by the way, I just changed it so in the next update there will in fact be an indicator in a given level which modifiers are in play. It'll even give you hints on what kinds of changes to keep an eye out for!
...and, looking back at how the level code works, given I had to in order to refresh myself on what changes are made in particular... I almost want to do a remix level set for the next update now which makes the stage changes considerably more dramatic, makes the first level a lot easier overall, and has a separate high score from the original game's levels.
