I spent most of my free time the last 1.5 years to make this 4-player iPad game together with my brother (developer) and two cousins (graphics).
Considering that it was our first Swift and SpriteKit project (my dayjob is programming business applications in Java), I am pretty proud of the outcome. It even got some reviews (one with a 92% rating!).
The only problem is, we completely underestimated how hard it is these days to get downloads for an old-fashioned "pay once for the whole thing" game. Currently we are in the process of converting it to a free to play model, hoping that more people try it. Wish us luck!
