Thanks for playing the game and thanks for the honest feedback. The first dialog is skippable, we added that during the bugfix session but haven't had time to add a prompt. You can skip it by pressing return on the keyboard.
In regards to the fullscreen: playing it not in fullscreen gives you a disadvantage in fights as you cannot see everything of the room you're in which makes it even harder to dodge. That's why we decided to go with start as fullscreen. I think the better solution is to add a proper tutorial for the controls which we are unfortunately missing.
The enemies have attack animations, although they are hard to miss. The staff wielders raise the staff before they shoot but currently, even if you see it, it's hard to dodge. We have a LOT to do when it comes to balancing and giving better feedback to players. For example, you can dodge by pressing space but even if you do, it's hard to tell currently where you'll end up so even though I've personally played the game for hours by now, I still don't really use the dash in combat. Only outside to go forward quicker 😅
That being said, I'm very grateful for your feedback as it helps us understand the players better as well as the issues the game still has!
