Well designed and thought out puzzles for the most part. The mechanic of combining elements to increase their size wasn't super clear however, and took away a bit from the experience. It makes more sense having watched the video link on the game's page, but still needed maybe one more tutorial level for that mechanic or something. Solid entry.

Thanks. Yeah, all the level design was kind of rushed in the last few hours before the deadline, and the way the more advanced mechanics are communicated is something I'm not super satisfied with as it is. One more level to introduce using the window to manipulate other objects before having to do it in a more complex way would have been good, but at the same time I like you to have to think a little to make that realization rather than just forcing it on you. That can be a tough balancing act.
