so..uh, clearly I missed kickstarter thing, is there a way to get access to "Backer extra rewards scenes" in the future?(´;ω;`)
That depends on what you are after.
The backer extra reward scenes were a reward for those people who wanted input into their own scene, that will then be in the game and playable by anyone who purchases a copy. I wanted as many of the kickstarter rewards as possible to enrich/expand the game for all players (extra characters / extra costumes / extra scenes etc)
So if you are wanting your own scene in the game, I probably can't oblige you now the Kickstarter is over, but if you just want to play the scenes that have already been backed, then you are in luck, as they will already be part of the game for everyone to see. ^_^
I hope this explains things and many thanks for your interest.
