While unique, it wasn't done the best way it could've been. Reminds me of google earth street view, but why include Galaga when you were having issues with the file size? You could've just made two separate game. On top of that the arrows that point to things in the room look like they were made in MS paint and were ultimately redundant because it's quite obvious as to what they are.
So it would randomly cut to Galaga when you hit an arrow, and the game is almost the same as the last version, except worse. The shots would get deleted unlike the last one which made it a little funner. Also you could get stuck and die multiple times resulting in an instant loss.
Weird combo.
