Thank you, everyone, for the kind & constructive comments! All 6 of us couldn't be happier that you've all had fun with it!
We definitely have plans for an improved version after the jam that will address concerns with balancing, difficulty & length - #1 priority for me at the minute is the new dungeon layout but there are plans for new enemies, mechanics and (of course) bug fixes!
Thanks again, and I hope you'll all enjoy V1.0 when it releases here on Itch!
