Some way of seeing what combinations you'd already tried, or at least which you had successfully combined already, would probably make this game a lot less tedious to play.
I totally dig the graphics and atmosphere, but sheesh, talk about hunting pixels. The difficulty of a game like this should be determined by the puzzles, not by how hard the objects you need are to see.
Lovely game, but it desperately needs a save function or at least some way to not perform irreversible action. Having to restart after half an hour of play is ... well... frustrating.
