 ## "Summer Santa Update 2022" (2022)
 
 On Christmas 2024, I made an adaptation of the

+game ["Summer Santa Update 2022" (2022)](https://spectrumcomputing.co.uk/entry/39005/ZX-Spectrum/Summer_Santa_2022_Update)

 by [Paul Jenkinson](https://www.thespectrumshow.net/). This adaptation is optimized for the ZX-Poly emulator,

 limitation where gameplay is restricted to three sessions. This may be a bug in the original code.
