Great game! I loved the visual style, both in terms of color palette and character designs. Cool music.
Even with the secret sword I still died quite a bit in the game haha
I think the only comment I have is regarding the terrain attack command; being a double-click jump sometimes gives the impression that it's a double jump command when it's actually the opposite. But it's nothing that's a problem, maybe it's just a matter of getting used to it. Again, great game, congratulations!
