or something similar to partecipate to retro snake jam.

Grazie Marco.
Ma merito va anche a Mario Morra che ha riprodotto la musica del coin up.
Dovrei comunque miglioralo e aggiungerci livelli ... ma si sa le buone intenzioni non sempre superano la fase dello slancio iniziale

Classic hangman game
The player has 5 attempts to guess the hidden words and to score as many points as possible.
Each guessed word is an assigned point.
The words are in English and their length starts from 5 up to 10 .... but it will not be so easy to advance a level, every 5 words you guess increases the level and the length of the word to guess.

Using the suggested code to develop a game i realized that a game that works perfectly on vice , it freeze itself at beginning on the real hardware and in some other emulators.
In this case the game is eligible for the cassette 50 compo?

I used the Shallan code against this emulator (but the problem is in the real hardware too) : https://lvllvl.com/c64/

Loading the generated prg it freeze and looking at the disassembly i see that the execution is in an infinite loop at $E5CD ,:

this is the pure Shallan code converted for cbm studio asm (DASM):

ENTRYM1 = Entry-1 ; Entry point minus one for the stack hacking

*= $120
Entry
ldx #$1F
txs ; Forzatura dello stack pointer per abbassarlo a $100-$11f
; ---------- Codice di partenza (205 bytes fino a $1ec)

Loop
inc $D020
jmp loop
; ---------- Fine codice di partenza --------------------
*=$01ED
; Quest’area di memoria può essere usata per le variabili a run time
; Una volta che il programma è caricato (1ed-1ff = 18 bytes)
; è stato sovrascritto dal processo di caricamento

*= $01F8 ; Sovrascrittura del vettore di ritorno nello stack
byte <ENTRYM1, >ENTRYM1 ; Stack hacking

* = $200
;143 free bytes here
byte $8f, 0
*=$028f
byte $48,$eb //Prevent keyboard jam
;131 free bytes here
byte $83, 0

*= $0314 ; Vettori per IRQ, BRK e NMI
byte $31,$ea,$66,$fe,$47,$fe
; Vanno mantenuti anche i seguenti Vettori
byte $4a,$f3,$91,$f2,$0e,$f2
byte $50,$f2,$33,$f3,$57,$f1,$c1,$f1
byte $ed,$f6 ; vettore di STOP - essenzialmente per evitare JAM nella memoria

; 3286 bytes liberi per tutto ciò che si desidera
bytes $00 * 3286 ; Riempito di zeri

taht part of memory seems rewrited after program starts ... i tested avoiding 02a1 initially but placing sprites data at run time . Sprites show an Hole!

There is a little problem on your really helping code

if i place a value $FF (but i suspect <> $00) in $2A1 :

        *= $02A1        
        byte $FF

your example freezes!
