This is so cool! So far, I haven't seen a game that uses an isometric point of view and uses layer masks, so that's really creative. Furthermore, I thought the graphics were really nice and polished. However, a couple issues I have is the camera movement on the main menu which is a little jarring, and the music not continuing through each level. And also maybe you could spice up each level by making the player look for a different color each time for example instead of always looking for red maybe one level could have looking for blue or green. But even without those, this is still great, so nice work!
