Just finished playing a casual run of the beta, I love it! The concept of stealing Pokemon is so clever, and the execution of it is very well done. While playing, I did notice a couple of things:
1) The Pokemon on Route 7 are still in the normal levels (~22), which is very high, considering it's available to the player as soon as you get your first two Pokemon. i don't know if this is a mistake or done on purpose, but just maybe something to consider in the future? (since it seems like many are exploiting this to beat Red, etc.)
2) In the department store, the text for the Thunder Stone is glitched (I think it says "Thunder StoneWater Stone", and covers up the price, and also leaves the text box towards the end)
3) I like that you left the Eevee in there c: Also, the lowered encounter rates in Mt. Moon are great, it's nice not having to run into Zubat every five seconds.
4) I think someone mentioned this already, but there's a slight inconsistency in the text at Mt. Moon, where Red defeats the scientist and takes the fossils. In the original, Red takes one and leaves the other, and in this version, the text is the same, and shows that one fossil is left, but Red still takes both. Either way is fine honestly, just the way it is now is a bit contradicting (it's a pretty minor detail, but I know how easy it is to overlook the smallest of details sometimes c:)
I think that's about it. Just a few things I noticed/liked about the game. You mentioned something about finals, good luck with those, I know how you feel! And if you want any help with anything in this project, I would be more than happy to help (but I understand if you don't want the help as well). Either way, I'm looking forward to the future releases of this c:
