Managed to beat the dragon, but the game froze, so sadly couldn't get to experience what the ending is like.
The art is nice, and I liked the retro music during the boss fight. Although I can see that there's scaling issues with the game and it doesn't fill the entire screen.
I quite enjoyed the dragon boss fight, although with the amount of health the boss had, I think a second phase would've been nice to change things up halfway.
