I like it. I wish they'd bounce off each other too! - to incentivize getting em into the same zone.
jmclnx•3mo ago
Very Cool and quite fun to play with
ninju•3mo ago
How do you win a level?

I trapped the critter with painted lines but when the time expired it said I lost :-(

ninju•3mo ago
Ah..you have to trap them REAL tightly and then they explode :-)
stevekemp•3mo ago
Helps to hold the button down and shake over the circle - if you don't mouseup it doesn't count as a new stroke.
deepanwadhwa•3mo ago
Nice find, there is a limited length for each stroke though :)
LoganDark•3mo ago
I just predict their path and draw a very tight circle and they explode in just one or two draws :)
hooverd•3mo ago
It's easier to keep bisecting the area vs trying to draw a circle.
nikolay•3mo ago
Reminds me of Xonix [0]...

JezzBall was also pretty similar: https://en.wikipedia.org/wiki/JezzBall

Jezzball was a TI calculator classic.

xp84•3mo ago
This is what I did instead of learning AP Calculus :D
EForEndeavour•3mo ago
This is so nostalgic. I remember feeling like I was so good at Jezzball. In later levels I'd start a wall near one corner of the screen, closer to one edge than the opposite edge, to ensure the shorter wall would connect, and sacrificing the longer wall. The surviving wall would create a "corridor" in which to trap balls with tiny horizontal walls, often such that they ended up completely stationary.
4cidBurn•3mo ago
Yes, this game is quite similar to JezzBall, or to a more modern example, Just Fillin’, which used to be available on the iPhone. I remember playing JezzBall back in the day on a floppy disk, and Just Fillin’ during the early days of the iPod Touch. It’s no longer available, but when I mentioned it, my 11-year-old son tried to recreate it, and honestly, I think he did a pretty great job.

Just Fillin’ iPhone gameplay can be seen on YouTube at: https://www.youtube.com/watch?v=zqvnk05iTbs

My son’s game, Bleachclaw Bubble Bash, is available at: https://lotsofnoise.github.io/

Xonix is listed as a remake of Qix. https://en.wikipedia.org/wiki/Qix

I encountered a version of this game sometime around 1990 and played the hell out of it. Since I don’t see any remakes from around that time, and I never had a Game Boy, I might have found it on a BBS, or a discount rack. There were a huge number of people briefly playing another game in this genre sometime around 2004, with lots of pretty colors. Everyone was playing it, and then they weren’t. I didn’t because I’d already played the original enough for one life. But I can’t find it in the list either.

dddddaviddddd•3mo ago
Reminds me of the Brandon Sanderson novel, The Rithmatist, where creatures are also trapped in drawn shapes.
dddddaviddddd•3mo ago
Overlapping zigzags quickly trap them. Since ‘trapped’ appears to be determined by the rate of bounces, you just need to divide the area as much as possible.
aiiane•3mo ago
Resizing the window smaller makes the game a lot simpler.
devjab•3mo ago
It does. There are 100 levels.
datadrivenangel•3mo ago
You can resize the levels to basically zero and instantly win each level
blahedo•3mo ago
It's giving Qix, a little bit, although the critter's different and the lines are way more freeform.

Bug, I think: the critter definitely can cross some of the paint lines, which was a little unexpected. It slows down but then it's on the other side of it.

ge96•3mo ago
I drew a circle around the critter and it was trapped inside it, I didn't win? Did it in 4 strokes
Terr_•3mo ago
Apparently you have to subdivide the areas so finely that they don't have enough room to exist.
theturtlemoves•3mo ago
Fun game.

The collision detection seems to have the same problem as the yin yang game that was posted a while ago: The critters sometimes cross the lines. I wonder if the root cause is similar, having to do with this being a browser game?

Nevertheless, fun little game
