My course is quite simple (partly because I love Aingingein). I've used flaming hoops for my version, positioned so that the flyer must zig-zag, requiring a lot of sharp steering and agility as well as speed. After the starter three hoops the player will weave between the others, looping back after the last flaming rung for a total of three laps. After this, they can throw the Dom through the final, golden hoop. The player with the lowest time (after any time deductions) is the winner
Instead of being anchored to the ground in anyway, the hoops are free floating and liable to bob up and down slightly, again forcing quick-thinking as well as quick flying.
My main addition is that of a phoenix. Able to disappear in a flash of flame and reappear elsewhere means the game bird can rest on any one of the rings and quickly appear on another. This can be both positive and/or detrimental to players. On one hand, if they fly through a hoop the phoenix is resting on, their overall time is reduced by 5% at the end (the more this occurs, the lower the time) on the other...well this IS Aingingein. If they fly through a hoop as a phoenix is flaming up to disappear, they could be caught up in the resulting fireburst. They may also be distracted by its sudden appearances and disappearances and end up burnt by the rings themselves. There's also the added need to dodge the game bird's long tail to avoid burns. Luckily, the addition of the phoenix means that any grave injuries can be seen to quickly with a few tear drops.
Obviously the lack of domesticated Phoenixes makes this version of Aingingein difficult to put together, but hey, maybe the Motohora Macaws will let us borrow their mascot, Sparky!
