Future "ta" tense too early
There were only a few questions through out the early levels of the tree which used the ta future tense unnecessarily. I guess this isn't necessarily a problem but it seemed out of place especially since there is a whole section of the tree later dedicated to the future tense.
I really don't see a problem with it. It doesn't hurt to encounter things before you are taught them. The hover should help you with them. I actually like it.
