there's no big green button for the demo download on the store page :( first I thought it was like 2048 with birds but the city stacking and entity behaviour is interesting. It seems like at a certain point your birds will stop combining. also it didnt detect my resolution (1440p) and launched very small and blurry at first. seemed to be getting a popup window during play that would start to appear then disappear without saying anything. I think it was telling me im 2 gud...
