Hi Tchey!
Thank you for playing and giving feedback! I'm very glad you like the game. Let's get straight to the points:
1) You can already use the arrow keys and the numpad (for skills) right now. I agree that this is also not ideal but it's an alternative for anyone not having qwerty layout. I might look into keybindings later.
2) Yep, I try to add basic options for sound controls and fullscreen in the next update.
3) It's already in the game but more or less experimental, hence no "documentation" ;) You can press the Page up/Down keys to zoom in/out. You may or may not experience some minor pixel rendering issues.
4) I'll see what I can do about it :)
5) I have save slots on my list for quite some time but as no one ever requested this I thought I might not need to implement it :D But I'm glad that you bring it up. I think Colmen provides some replay value in terms of different builds and I will try to enable save slots in the next update.
6) Nah, those crits need to rumble!
7) I will consider adding raw numbers for the health/mana orbs.
8) Hmm... I don't quite understand this point. You've found it difficult to play with the bow and want it to get nerfed so that it can not be used in melee (distance=1)? I'm sure I misinterpret something here ;)
9) I want to wait for a lot more player feedback before deciding on any changes here.
Again, thank you so much for taking the time to put this feedback together! Much appreciated!
