When Is The New Update Coming Out.

I don't know.

Are you working on the next update? Tell us little things about the update.

I am working on the next update, albeit not very often. The next update will feature a lot of performance improvements, a few new levels, two new stages in RTI, and bug fixes.

Is it possible to get 1000 coins on road to infinity mode?

Don't see why it wouldn't be. There's no hard-coded limit.

so I can get 1000 coin in road to infinity mode.

Yes. It's possible.

It broke for web.

"Your browser does not support WebGL"

Make sure your browser supports WebGL and that you have it enabled. You may need to update it for full support.

Like, it was working completely fine, but then suddenly, WebGL games stopped working.

That happens sometimes. Double-check that your browser and OS are up-to-date.

How did you do the different games styles. Also, where do you announce the updates.

To make the different gamestyles I made a script that checks what the current gamestyle is and replaces the sprites of each level object based on a preset list. Updates for the game are announced on my YouTube channel ( and the SMBS Discord server.

Thanks! Hope the next update is good!

and i belive wev'e met on scratch my user name is: cappa723 if this rings a bell its because we have met

so there is a glitch (or at least with me) that makes its SUPER lagey and makes mario go back and forth and iv'e tried everything i i can't seem to fix it so can you please try and fix that?

A bunch of glitches that cause lag will be fixed in the next update

So glad it came out! been following this project for a while

I noticed that in 2-5 there is a pipe that says thx burnttoast312 (at least I think it says that). Is burnttoast312 the person who helped with the level?

Yes, they designed the first half of that level (2-6).

Good job!

Really random, but is the title screen theme an original composition or a remix of another song? just curious, it sounds familiar.

It contains parts of the Super Mario Land 2 Space Theme

ah. That's where I heard it.

Your controls can be changed in the settings

The Mac-OS version will not open.


What error message occurs when you try to open it? I don't have access to a Mac so I can't debug it very easily.

"The application "SMBS-v020-Mac" can't be opened"

It also says:

Safari can’t open the file “SMBS-v020-Mac” because no available application can open it.

Me to. It won't open it and what app am I supposed to get?

I wasn't able to directly test the Mac version. It should download as a .zip that contains an .app file.

Okay. I will see if I can play it.

When I downloaded it can't open it.

Which version (Windows, Mac, or Linux)?

MacBook Air (Mac)

Better then I could of imagined!  


Downloading before Nintendo takes it down

Good idea!

Me to but I have a Mac and it's not working.

That is not how that works

Sadly i can't play this right now. Mabey later!
