Yep, there's a missing GOTO that would force a return to the start of the control cycle at 1650 when all the functional directions are examined. The program slips into a mini subroutine at 1720 without opposition and runs into a RETURN command which causes the error. Try this line, see if it helps:

1715 GOTO1650

I'm OK with that, however be sure you tested the game meticulously, because the sprite usage limits free memory and if I remember correctly, the BASIC data can spill into the sprite data easily if you expand it. OR you can be a pro and relocate sprite data, like I obviously didn't.

Well, if the concept is simple but captivating, there's no reason for it not to exist on a 40+ years old microcomputer. It was also fun to code.

You can play it online here. Gameplay is a bit different because I wasn't able to implement falling tiles without sacrificing speed significantly (it's doable in ASM but that's too difficult for me).

This one is begging for an 8-bit port.

Ohoho this game is ripe for 8-bit implementation :)

Oh thank you! I was tempted to spill the beans on it, because ORDER is one of my favourites. But I'm glad I didn't.

Thank you a lot. Can't blame you for not playing it. Apparently it was lost for a long time and was only discovered recently. A major reason for porting it to the C64 was to ignite some interest in the original as well. Your video is a great help in this endeavour. Keep up the good work!

Hi! I've sent you my e-mail address on Twitter/X via DM.

You need ten planks for a raft, and I think it is possible but you have to deal with the risk of being more daring with the sharks. The 1-to-9 positions in fishing are fixed and I made no effort at changing it, however I restored an original feature of the game that was missing from the 1985 version: the fishes now swim at different depths so even though the game doesn't really try to deceive you, your perception of left-right is thrown off a bit by the small difference of depth.
