The game doesn't have too much game play on its own, just holding down W and D a lot. What you call a bug, having to go back and forth and growing larger and smaller to traverse land, felt like it could be game play itself. It almost felt like a puzzle at times, trying to figure out how to get past a certain patch of land. A puzzle until the player entirely disappeared but still. 

I played the game in a tiny montage I made of a couple of games. You can find it here or on my channel
