Making progress with my port of #PerilousSwamp to Tree Forth on #Minstrel4. #retrogaming

Testing out my new #MinstrelInputMonitor from @tynemouthsoftware.co.uk for a game of #PerilousSwamp. #zx81 #retrogaming

I am currently enjoying the simplicity and early aesthetic of #PerilousSwamp. Also, is the only game I have seen with checksum to confirm loaded correctly! #retrogaming
