This game was really fun! It was a bit hard to read at certain points, for instance it was hard to tell how much HP I had, whether or not I hit the enemies, whether or not I bought something, but I think a majority of these issues would be fixed by adding some sound effects!
I absolutely loved the final boss, he was super tough and I liked how he got stronger / faster as his health decreased.
Very fun, and the gambling mechanic was cool but also a bit unintuitive. Great use of the theme!
