What the “Loading 0%” Screen on Jelly Mario Means

Updated

The “Loading 0%” screen is Jelly Mario’s loading indicator: it shows that the game page has opened but the game assets have not finished loading yet. A value of 0% means nothing has loaded so far. Wait a moment, and if it stays at 0%, reload the page. The same screen also shows a Sound option and a Tweet link, and the page states that Jelly Mario does not work on mobile.

What you are seeing

Jelly Mario is a browser game described on its page as “Something is VERY wrong in the Mushroom Kingdom…” and labeled r15 (pre-alpha). The loading percentage is the game’s own progress readout, not a browser error page.

Element on screen What it means
“Loading 0 %” The game has not finished loading its assets yet
Sound A control for the game’s audio
Tweet A link for sharing the game
“Jelly Mario does not work on mobile, sorry :(” The game is not supported on mobile devices

What to do if it stays at 0%

  1. Wait briefly. The percentage should rise as assets load. A short pause at 0% is normal on a first visit.
  2. Reload the page if the number does not move after a reasonable wait. This restarts the loading process.
  3. Use a desktop browser. Because the page explicitly says the game does not work on mobile, a phone or tablet is not a supported way to play, and the loading screen may never progress there.
  4. Check your connection if reloading does not help. Since the indicator measures asset loading, a slow or interrupted connection can keep it at 0%.

What the 0% does not tell you

The page does not explain why loading might stall, and it gives no file sizes, requirements, or troubleshooting steps. The percentage is simply a progress signal. If it never advances on a desktop browser after a reload, the page itself offers no further guidance beyond the mobile warning.

The “pre-alpha” label is also worth noting: this is an early build, so rough edges in loading or performance are part of what you are trying.
