What's wrong with ZX-Nibbler?
This 2019 game from Hebdologiciel is potentially the greatest ZX81 arcade conversion of all time.
It's fast, responsive, plays exactly like the coin-op and appears to have pretty much the same levels.
There are only two things wrong with it. One is that it's annoyingly not centred on the screen, and the second is something I only discovered while trying to fix the first one, and it's that you can't finish Level 5.
You can collect all the items, but the game doesn't realise the level is over at that point and just keeps going until you run out of energy and die.
At that point it'll start you again in an empty level, and of course you'll die again until you're out of lives.
Can anyone figure out what's wrong?

I noticed Level 5 was the only one with different kinds of objects in it:
So I fixed them all to be the same, but it made no difference.

Hi,
[Edit: I had to have a look to the BASIC program, it seem to be another bug!]
Something's wrong in your type-ins, it's better to download my release, or change the BASIC listing between the line #530 & #548.
The right graphics are:
Have fun.

Thanks JohnsBargs !
Is there any changes?
I will update the web site later... (Something's wrong with the bonus display too)

Works beautifully now, many thanks
I had noticed the odd bonus thing at the start. Will see if I can fix that myself, and then get on with trying to sort out the centering.

Meanwhile here's an English-translated version.

New problem: Stage 8 also seems to be impossible.
The trick is that the food you have to collect is now the "opposite" hash character, which is sneaky and clever, BUT there is no route from the bottom half of the maze to the top. All of the middle line is "wall" hashes.

Fixed that by adding a couple of A hashes in the central wall and the level can now be completed, but the game then screws up when you go to the second loop - the screen isn't cleared and it crashes with a C/6040 error when you die.

Okay, fixed that with some judicious CLSes. Now just got to fix the score being screwed up when you beat Stage 8, which may be related to the bonus intro thing.
