FOSS Engine Royale (2020) -- HaxeFlixel Lap

I'm pitting 8 FOSS game engines/frameworks/libraries against each other--by making breakout in each of them with a 6-day time limit. This week is HaxeFlixel, an open-source game engine based on the Haxe language. The end result is pretty close to DFGame, but due to physics issues the moving bricks had to be made stationary.
