Thanks for playing, and glad you enjoyed! Yeah I definitely feel as though there are issues with balance as well, although a game like this is hard to balance in such a short time-frame. Our thought process was that the fight would usually be beatable on a second attempt if the players didn't have the right build their first time since they'd learn what works through their mistakes, which to be fair is typical of the rogue-like genre, and that the game is short enough that that wouldn't be too punishing.
We will likely be pushing a balance overhaul, as well as adding in a few of the things we cut for time after the rating period ends, so stay tuned for that! Thanks for the feedback!
