Played your game on Windows.
First try with a gamepad connected: The mouse doesn't move from the center of the screen, and the gamepad barely lets me control the camera. I went back to the main menu, pumped up the sensitivity but it didn't fix a thing. Had to exit the game, turn off the gamepad and try again.
Played with the graphics on ultra and keyboard + mouse. First impression was nice, the game can look nice and your style is quite unique. The camera itself made a bad impression tho, as it kept snapping to those pillas in the hallway that leads you to the training room, although it was fine for the rest of the game as the scenarios were simpler. Adding some lerping to the zoom might help.
The game could use an "always run" toggle. The fire worm deals a ton of damage and I'd love to be able to enter combat mode by just clicking the left mouse button.
Main problem the game has is the combat, since it's quite mindless and button mashy. I'd try making Fygoon attack slower by adding some delay to the sword attack. That'd make his attacks get some weight and look stronger, while making each attack count more.
Aside from that, I was impressed at all the effort you've put into this. The cutscenes are cool and have nice dialogue, the levels are big and not too linear. My favorite part was bonking a dog with a mace and he having an animation just to react to that followed by funny cartoon sounds. Very charming.
Found no bugs nor performance problems.
Nice job! I wonder how it'll turn out. It's quite promising and I'm amazed that some so young is able to pull this off.
