Great use of theme! This really does have the appeal of watching a little train set go round and round. It’s very relaxing in that way (the music helps). I will say that aside from the trains and boat, the background is busy enough that it’s hard to tell what’s happening mechanically. Like I’m not sure whether the faint rectangles are teleporters, multipliers, bumpers, or death zones, and as more and more balls spawn in, it becomes even harder to tell. At the same time, though, it’s easy for me to just zone out and enjoy the whole experience. Great vibes, great job!
