Help with Inventory Rocket Parts

What I’m trying to do is move the forklift sprite around the screen and collect rocket parts and send numbers of parts collected to Micro:bit for data logging. I have 2 parts as assets and now need to replace food with parts. I need to get rid of any un-necessary code; it is just too confusing if not needed. Any help would be appreciated: https://makecode.com/_5bVcpHADydga
