Pretty impressive for your fist game and only 9 days! you can be proud.
Combat felt really well, here are some suggestions I would do:
- When I hold the block key the hero blocks in quick succession, I would keep the shild up if the player holds the button but stop the stamina regeneration. Also all damage (or a part) while blocking is count to stammina not health
- The roll can be shorter, as long as there is no enemy which requires the player to cover a big distance (like a big enemy)
- Heavy and slow attacks or maby a range attack could be fun
I also love the artstyle, but it seams you used sprites with different resolution. This can be ok but try to keep at least the characters (enemy and player) the same size and background the same size.
One more tip: try using text boxes for popup text, this makes the text more readable.
Keep up the good work and have fun on your futur journey as a game dev :)
