But Cavanagh battled through all of this, and finally released the game via the Google Play store earlier this week. And to his surprise, it was most definitely worth the effort -- the game has now sold more than 25,000 copies on Android in just the first four days on sale, easily besting the initial days of the iOS version.
"I'd heard from other developers that Android is a much smaller market than iOS, so yeah, its success has been quite a surprise!" he tells us. "It's not really fair to make a direct comparison, because nobody had heard of the game when it launched on iOS - but so far, the Android launch has been bigger than the iOS launch, which I would never have expected."
Anyone who follows Cavanagh on Twitter will know that he's had numerous problems with getting Super Hexagon to play nicely on every Android device, with the Google Nexus 7 tablet in particular causing such deep problems that he was eventually forced to say that the device would be incompatible with the game.
"I think developing for Android is basically a lot like developing for PC," he notes. "Even if you can get things working nicely on 99 percent of devices out there, there's still a good possibility you'll encounter problems with odd devices, just because of how many different types of Androids are out there."
Yet despite these issues, the VVVVVV developer hasn't been put off the platform. "It hasn't been too bad though, considering," he adds. "We've already managed to fix most of the main device specific issues since launching a few days ago."
As for Cavanagh's mobile future, there's no doubt in his mind that he'll be aiming for both iOS and Android releases for his next games.
"I think it was well worth the effort," he says. "I'll definitely be bringing any future mobile games I make to Android."
