Ok! I managed to reduce the images a lot and separate them into smaller pieces.
It was GREATLY reduced, so now it works on browser!
I exported it to HTML5 and uploaded to a server (Netlify, as suggested by Construct) and I can run it perfectly on my MacBook (on Safari).
So I decided to move forward with the project. Since it "has" to be on the Raspberry Pi4, I moved the .zip file downloaded from Construct (with the HTML5 package in it) over to the Pi and extracted it there.
When I double-click the index.html, the browser comes up (Chromium) the Construct icons pop up and.... black screen. For ever, by the way. I left it for a loooong time and nothing. Then I did the same on the MacBook, extracted the .zip, double clicked the index.html and same result. Black screen.
I then tried using the Netlify version (since it's deployed somewhere, maybe that would be a difference) and the Chromium on the Raspberry Pi4 doesn't handle it. it tries to run, it loads but every other frame in animations are black (which made my BG blink on and off like crazy) the sound is super choppy and the whole system becomes extremely sluggish and unresponsive.
I can't really figure out what am I doing wrong.
Any ideas? And how to fix it?
Also, is there a way to "make the HTML5 folder into an executable" or something, that I didn't do? (So that it would consider as if it's deployed and run, or something like that?)
Thanks once again! :D
