I feel like a trick was missed here with a "All your base are belong to us" reference.

Only because I am out of touch, and never played Zero Wing, my misspent years weren't in the 90's :wink:

Also no emoji for Zero Wing :wink:

Nice work!!

FWIW, there's also a Base 85 which will give a slightly more compact representation than base 64:

it compiled just fine :grin:, i just deleted the .rush directory and rebuilt the extension

16

My guess is there is something in one of the additional "base" java files when used.

17

:question:

18

It might compile OK, but when used there may be problems.

19

I found this:

Short lambda expressions:

long zCount = chars.chars().filter(c -> c == 'z').count();

I also checked that you had not enabled Java 11 support that Rush offered.
Also these werent supported until recently when AppInventor upgraded their systems, so it should work fine from now.

20

To be more on a safer side, just replace

long zCount = chars.chars().filter(c -> c == 'z').count();

with

        long zCount = 0;
        for (char c : chars.toCharArray()) {
            if (c == 'z') {
                zCount++;
            }
        }

and simply compile again after deleting .rush directory

I will have a play with it at some point, also need to add base 91, which is lurking in a separate extension of mine. Thanks for taking the time to look things over.
