More monster varieties with their own unique weaknesses
Some powerups to take the edge off. Getting overwhelmed without a hope of escape ain't much fun
Some basic context like who we are and why we're killing blorbs in a dungeon. That's just me though.
I like Washington's suggestion of classes, but it might be a pain in the ass to balance that.
Overall, it's decent and I await to see what you'll bring in the next update.
