This is a survival castle defense game.
From what I could tell, was that this more like a ‘demo’ of what’s possible, like a prototype.
The scene isn’t particularly stabilized in the real world, but that is common for the apps I’ve seen, so it might just be the iPhone SE, and ARKIT, as apposed to the developers.
Aside from those few glitches, this is an excellent use of ARKIT! With the ability to move the phone in many ways, to see the battle field, is entirely intuitive. The inputs are out of the way, and it isn’t difficult to collect coins, or target the invaders.
If I could see more from this game, perhaps I might have missed some of these features, I would have the ability to see my score, to move into a main menu screen, to adjust the location of the battle field, to have upgrades, and I would want to see a multiplayer version. Perhaps battling each other, one invading while the other defends, or both hold the fort or mass an army to get through the walls.
Wether this would be incorporated with this game, or as an abstract feature for other systems, I think it would be cool to have multiple people use their phones to create interactive objects and boards, that only they can see, with other things being visible across all devices.
