I liked the art style, animation and rewards, but agree there could be more enemy types.
Loved it! The map is very expansive, there's a lot of areas to discover and there's a choice for the player on what upgrades to pick. If I had one criticism I would say that it took me a while to figure out how to shoot arrows. Also a minimap might be a cool addition, to help with navigation. :)
I like the resource management system. I think one improvement if you take this further is to make the teleport arrows a bit clearer. I do love the different event captions you've made though. :)
Really cool art style and I like the puzzles. :)
