Thank you so much for playing, and for passing along this encouraging feedback. Glad you liked the concept!
The big beastie that killed you is actually the first of three bosses! Still not sure if we've made the game too hard for people, but you can also get pretty crazy strong with some of the combos that are possible.
Game page should be public soon, just adding a little visual polish to the dungeons and then unleashing this baby.
Thanks again!
