Maybe in the colour changing part, you can add colour changing decoration, and a colour changing background (except the colour switches would be different from the objects).
This x1000. Many people don't get this. As a player I enjoy wayyy more levels that require skill rather than effect stuff that just lags the shit out of my pc. Not everyone has a NVIDIA GTX680 pals, also those levels look ugly AF (IMO)
Since when did more triggers instantly make a level better? There's no point in hard work on a level's effects of the level isn't fun.
Sometimes, yeah.. sadly, other times (aka most of the time) they just make the level buggy and annoying. :/ Imo, Unity by Tri and BunnyGame is, to date, the best combination of cool effects and fun gameplay. Lots of levels are much more intricate and cool-looking, but just aren't fun to play.
