I appreciate your very detailed comments.
The background and monster graphics are my own creation, though, The fonts are free fonts called BestTen. The credit is given on the game page.
As for the controls, the main reason is that I was familiar with them. I played other people's works in this jam, and I regretted that the controls of this game were not standard. This one will be updated post jam with an option to switch between strafe and turn.
I understand that you want to get all the items from the chests. This is due to the game design, with limited items and limited durability, and we want you to be able to choose which items are best to get in such a situation.
I am also sorry about the difficulty level of the game. I apologize for the inconvenience caused by the lack of time and the inability to implement checkpoints and other features. I hope to improve on the things you mentioned, such as displaying the remaining HP of enemies, in future updates.
Thank you very much for playing!
