Dat purple plant puzzle dou, it might be a tad too complex for such an early stages quest. Dev might want to consider changing it to be similiar, but not nearly as difficult to understand (especially given the fact that their English isn't ENTIRELY fluent, and it's enough to make it difficult to follow the instructions). Personally, I'd like to see them posting a walkthrough so that very little needs to be changed whatsoever, but that'd probably be something they might consider doing with later versions of the game.
Either way, it's a game that shows a great deal of promise and it makes "little me" very happy! ^_^
