＞Why is it taking us longer than we thought to get the port fully polished?
＞Honestly, it’s just that as first-time developers we built the game in some strange,
＞unoptimized ways and to get things running smoothly and consistently we need to
＞sweep back through and rewrite or fix bits and pieces.
＞It’s an involved process, but we’ve learnt a lot for the next project and it’s a big relief to
＞get everything cleaned up nicely!
