Howdy Crepecroop,
This is a very fun game you've created. The gameplay is fun, I had a great time exploring the world looking for secrets, and the final boss was a fun fight both at the beginning of the game and after clearing both dungeons.
I haven't done much speedrunning of this game yet, but it has been enjoyable to see how fast I can beat the final boss when skipping everything else.
I wish you luck with any other games you might make in the future.
A few things of note:
1. For some unknown reason, the game always goes fullscreen whenever I enter a dungeon.
2. When speedrunning, it would be nice to easily start from the beginning from the main menu instead of refreshing the page.
