This is one of my first experiences of itch.io, you had some what appealing design so I thought I'd give it a try!
All my criticism below is with no ill intentions as I obviously would not expect a AAA combat/rpg title on itch.
I think the text you added was nice, but for such a simple game the tutorial aspect I found wasn't needed...
I would say the shop system could use work as I didn't understand prices or what I was getting.
The combat aspect I completely ignored as I found it did nothing for me...
Took me a total of probably 5mins to just run through it first try.
I like what you've done and look forward to future development from you! Keep at it bud!
