I'm glad you like the art of the game, it's one of the aspects I've worked on the most.
The first arrow jump is designed to make the player suffer a little and force them to try things until they master the jump and time control. (Although the player can pass the obstacle without using the special ability.)
You can defeat the final boss at any time and in different ways, I see that in your attempt he decides to resort to the "pacifist" route. :D Although the ideal would be for the player to die a couple of times so he could explore the rest of the map and come back much stronger.
It is still a prototype, although if I see that people like it, I would polish its mistakes and make a proper version with everything I have not been able to add and the feedback received.
Thank you for playing it and reaching 100% completion!
