I'm Making a Small RPG and I Need Feedback Regarding Performance

This past month, I've been working secretly on a small RPG game.

While the game is not ready at all and I didn't plan on talking about
it, I'm now kind of forced to.

I've been using JavaScript + the KAPLAY game library to make this
game but I've been experiencing performance issues. However, it seems
that others aren't experiencing them so now I wonder, is it just my
machine?

I'm using a Macbook Air M3 with 16GB of RAM. Normally, things should
be smooth and they are when playing the game in the browser via
Firefox.

However, since I'm making this game with Steam in mind, it's
especially important that the game performs well when wrapped as a
desktop app.

For this reason, I decided to reach out to you, my audience, for
feedback. I have included a build of the unfinished game for Windows,
Mac and Linux. It would be very nice if you could try it out on your
machine. Additionally, recording gameplay and sharing the link in the
comment section of this post would be greatly appreciated.

Here is the link to the game in its unfinished current form : https:/

Below is a gameplay video to give you an idea of how the game is
supposed to be played. You can move around with arrow keys and enter
battle by overlapping with a star in the overworld.

Performance issues, if any, occur mostly during battles.

Thanks in advance!

Export Web Games for Desktop in One Click

In a previous post, I tackled the various options one could use to
make their web games playable offline as installable desktop apps.
This would enable using web technologies to make games that could be
sold on a platform like Steam.

You Can Now Make PS2 Games in JavaScript

I recently discovered that you could make PS2 games in JavaScript.
I'm not even kidding, it's actually possible. I was working on a
project and had my phone near my desk when I received a notification.
Upon further inspection, it came from itch.io which was a platform
where I usually published most of my web games.
