I just realized the first level looks similar to the ending of the last level. just a neat easter egg in one of my favorite games to play at school lol
Funny you noticed that, since it is technically the same level! In fact every level in the game is on the same map; the last two levels consist of retracing through the entire game to reach the start. Here's the map of the entire game, one of the most fun parts of designing the levels was fitting them into a single space and connecting them together. you can actually trace the path from beginning to end through each level.
And it's wonderful to hear that you enjoy the game so much, thank you!
