If you enjoy pushing-puzzle games, you will probably enjoy Heartlight. It is indeed light-hearted puzzle fare from Epic Megagames (one of their earlier games). The graphics are okay for a puzzle game (VGA), and there seems to be a good number of different levels to try. (Note: You have to run SETUP.EXE before you can play. Also, if the game seems to run very slowly, try running SETUP.EXE and selecting NO SOUND. That fixed the problem on my computer, at least.)
