Hello, after last changes (a lot of) I cant download utf file, it say something about compile errors.  
But debuger is silent.  
After changing to javascript mode it firstly say error in arcade-text extension, but after 1sec it remove error notifiacation from it and put it on some pygamer’s modules like `control.ts` (`base` folder), `targetoverrides.ts` (`screen----st7335` folder), `melody.ts` (`mixed----smd` folder), `controller.ts` (`game---hw` folder)  
But then I will click on problem file, notification is gone without any tips.  
Project saves (and playes first time before compiling) as usual, nothing wrong.  
What’s wrong?

After I maked simple mechanics for 1st level, everything is ok.  
But after I use changing tilemaps as my app became to playable in player but its not compiling.  
I didn’t want to post it earlier then it should, but of course you can`t help without looking at project.  
I really don’t know what is wrong.

(you can skip 1st intro by A button. For going to first level go to bench on the north, you`ll se a floating hint)

Ah, if you open the console and press compile this is what I get: (Chrome inspect tools)

If you look at one of the last lines outputted during compile:

```auto
pxtapp.js:1 error: pxt_modules/arcade-text/main.ts(1,1): error TS9200: program too big by 20658 bytes!

```

Your program is too big. ☹

There is - the combination of lots of code + lots of images probably too much for the PyGamer which I selected for the hardware. For large and complex games you are basically out of hope (like yours) because if you don’t have enough program space, it’s highly unlikely that you would have enough RAM for those little devices.

This option has been discussed before - sadly it is not possible. ☹

🤔 Where did you get 16kb??? The PyGamer, which uses an ATSAMD51 chip (also what device are you trying to build for? Meowbit? I use PyGamer because that is what I have) and has 512kb of flash. In my experience, UF2 files for the SAMD51s that are somewhere around or over ~750kb will just fail to flash.

Can I somehow oprimize game and save more memory?  
Pls look at project. Maybe creating images from code from array or something?  
Or it doesn`t change anything?

deleted some stuff and got less difference size.  
I looked at my project folder again.  
File images.g.ts and images.g.jres both 300+ kb. So images are most heavy.  
And its looks like their double each over. Why?

@UnsignedArduino, and I found a reason of part of lags in lvl1.  
Its because of 8x8 tiles 🤫  
Without them it stays at 30 fps (but I gues it should be more)

I updated. Deleted unused stuff and backgrounds from 1st intro, put them all to animation.  
It works.

Now project`s folder is 769 kb. But lvl1 requires more images we need to draw.  
And still no sound…  
And (idk why) really bad fps, 16 then image is appear and 12 then it redrawed.  
So I still need’s your help)

Removing all the big images is the only way I can think of ☹

Ok then.

can you comment this?  
or maybe proposition why it has only 30 fps with 16x16 tiles?  
It`s strange, simple menu with 3 animated objects has 45 fps, but lvl1 screen with no animation has 30 fps (with 16x16 tiles) and 13 fps (8x8 tiles)  
That’s not normal.

More tiles = more stuff to draw. Also, the hardware will always be much, much slower than the simulator. If you can get 30 FPS on hardware that is considered good.

To many sprites? My game lagged once because there were to many sprites

ok , if I want refuse from using 8x8 tiles (unfortunately, cause it’s perfect works in game cncept, but too slow).  
How can I replace same mechanic?  
Can I just use simple sprite, and get color of pixel which overlaps my projectile and redraw this pixel only?

Should it works?  
I guess this can free some space in project (by deleting tilemaps extension) and free more fps cause I will back to 16x16 tiles which will not participate in this level’s mechanics

It would be really hard ☹  
I would rather stick with the 8x8 tilemaps and have less performance because it will be easier to code.

Byt the way, thanks you for your scaling library.
