super neat game! i played through all the levels.
cool twist on the theme!
some things i'd like to see if you continue to work on it:
- i'd like the game to be larger (instead of having a big black border around it) and fullscreenable
- a hotkey to release the current thumbnail (without having to use it) would be handy
- a level selector and star system where you would get three stars if you solved the level using the fewest thumbnails possible
- the audio seemed quite loud to me. i changed my system volume so it was no big deal, but having audio settings would be really nice if it were a longer game, where i might be dipping in and out or listening to something else while playing.
- definitely more levels! i really enjoyed playing the game :)
