Snakes On A Cartesian Plane

If a snake eats a pellet in the forest, and no one is there to control the joystick, does it still score a point? There's no need to get philosophical with Netgrind's Snakes On A Cartesian Plane, but you do need to put your thinking cap on. Each level puts a twist on the classic snake game, like disappearing traps, weirdly warping walls, and twisted controls. How many points can you rack up?

The walls don't lead where you think they do.

Rattlesnake

Four squares that may or may not be food appear at one time.

Ringneck

Every other square of you is pretty much non-existent.

Like Mamushi, but you can't see the deadly squares at all!

Passage

Can't face left.

Pretty sure Ringneck is glitched. It's stuck at 99%, no matter how many times I hit my own tail, and 99% shouldn't even be possible to get because you need to hit your tail 50 times. It should be at 98%.

...Man, I wish there was an edit button.
There's also no mute button, and I'm not too much a fan of whatever style of music this is. It's not bad, though. And the game itself is pretty fun, and you can play as solid snake YES.

Reece don't know about the Ringneck yet but just hit + or - for volume

but *grins* this takes me back to my old Oric :)

@Reece, The percentage shown on Ringneck is glitched indeed, but the internal control is fine. Once you die 50 times by hitting your tail you'll unlock it alright. It's a bit annoying, but keep playing and you'll get it eventually.

The games themselves are pretty good, but what really amazes me is how the dev managed to create so many of them, throwing in twist after twist even when it seems there can't be anything else to change. 5 mushrooms for the great display of game designing!

This game is a bit of a misnomer: It's not a Cartesian plane as you loop around when you get to the edges, that would make this a Riemman plane.

So, anyone else beaten the developer's score on all 28 of the games? and then

that bottom-left space becomes "OoO" and when you click on it all that comes up is "QXDCDZSSAEQ" ... any ideas?

e7odie, I have the same issue. I got this surprise and don't know what to do. I tried some clicking and typing at some places but... nothing :/.

I'm pretty sure I am seeing some sort of bug in Rattlesnake:

If I try to eat a fake pellet (and harmlessly pass over it), then that space becomes an obstacle once I eat the real pellet.

This gets very frustrating very quickly--I think my high score here is only 6. Does anyone else see this?

@bubblecamera(walkthrough)
for plissken

you can see the deadly squares once each time after you eat a pellet

@OtherBill

does the fake pellet become an obstacle after eating the real pellet or does the fake pellet become an obstacle after you pass over it because if it's passing over then there is nothing wrong

@Bobin Hood:

They might become as soon as I pass over them--haven't tried to re-eat a fake pellet.

Still, between the old obstacles, the new obstacles, and the new pellets that I haven't tried yet, Rattlesnake turns into a memory test very quickly. :-(
