I'm just know this besauce I pressed every single key.
So lets beggin:

1. You can move with the ← and → keys
   
2. The X key is the most important key. With this key you can do mosly every action.You can attack by pressing X and ← or →. When defeted the 1st ememy you going to get into "the Labyrinth". The you can Jump by pressing ↑ and X at the same time.
   
3. You can Quit the Game by pressing F9
   
4. You can save too. But only if you are in the Labyrinth. Just press F3.
   
5. With F1 get into the keybinds layout

That's basically it. If you have any question or other keybinds that i didn't know just tell me about it.
Thx for reading this text.
Don't judge this is my first guide
