I must say the game is great, but here are some of the improvements and bugs that I feel that need to be addressed.
1. No voice acting/scripting. The game feels dull because there's no sounds. One suggestion is a cheer by the hero after defeating a mini boss/boss.

2. Spawning: Is spawning in the beginning always necessary? Look into unlocking spawn areas as the character progresses.

3. Courier moves to starting area. Look into sending the courier back to the shop instead.

4. Cannot click select courier, can only press F2. TAB isn't working either.

5. Cannot press shop hotkey to quick purchase stuff. I guess there isn't a stash. I guess this is something that is intuitive for most and going back to open the shop or selecting the courier to open the shop. It is very counter intuitive and disrupts the flow of the game. (It makes a difference to me though.)

6. Sometimes I the trees aren't dense enough and I walk through them hoping that there's something in the little forest but no, I suggest covering them up with more trees or placing hidden content? It's an adventure game mode after all.

7. The stairs at the right side of the radiant lake seems to be blocked off, is that intentional?

This is it so far, I've only touched a quarter of a map, will update with you devs soon. (:
