It's a shame you coudn't finish your inital idea, I'd love to play it, seemed quite fun. Still, congrats on finishing the game anyways, I loved the art. To be honest I didn't quite get the colors of the arrows and didn't had to do much to finish the level, but maybe I was really lucky xD
As someone said on the comments below, I think the game would be better without the 3 sec waiting mechanic. Because the player doesn''t really have the control it can be a bit boring waitig those 3 seconds. If not, some kind of reminder of when you have the power and when not would be nice too!
