Thanks a lot, we're happy that you liked it!
Yeaaaah, the systems are not polished, it was a lot of stuff to do, so we had no time to iterate many times over the stuff! With a slightly bigger team, we could have made it! The original Combat design was focused on "kidnapping" -- some monsters would carry the characters away (like Resident Evil 4) and the other sister would have to help.
I also wanted to create a lightgningbolt (stun in area) and a ground wall (protection), but yeah, it was a lot of stuff already for the 48 hours.
Again, thanks for the kinds words! =))
