nice challenging!


you shouldn't lose a power up when you get hit

This is very polished and a ton of fun.  Are there any good platforms to get in touch with you to discuss a business opportunity with your games?

This is the most fun thing you’ve published. (Not counting Poom) daggers was cool too. But this is awesome.

Got anything like this in the works? Or maybe more content for this like a new enemy type or improved enemy ai?

Was a nice game but you can get easily overwhelmed and massacred if you dont move forward step by step, killing a few enemies each time :-)

Very nice. but difficult to me.


Really fun game! The controls just feel kinda weird. damn those flies...




Morí en el boss, pero me divertí mucho 😁

the controls make me want  to die

Not bad, not bad at all


makes me wish i had a little handheld to play this on

Loved it :)

This was pretty great and I love the retro vibe! Coulda used more diversity but otherwise I had a blast!

This is so good and also so hard

Hi, Can you add .p8 file for rom.


I've added the .P8 file for download from the itch page.

It's also available to download directly into Pico-8 by typing "load #xzero" from the Pico-8 command line.

Thank you so much for this great game

I love the game but there are way too many enemies. Too many spawn at once on the same screen not giving you enough time to react.

Loved pretty much everything about the game, but...

after you get maximum gun level, the gun level thingies the enemies drop mean nothing

there's only two types of enemy and  one form of gun-- diversity would be nice

everything else was great, 11/5 would play again

controls were smooth

This comment going to be a mouthful so get like, that's it don't think I need to explain it.

amazing contra style game.. want more levels!

Is it possible to download a pico-8  "cart" version? Would like to play it on a player in Android...

Ah, found it on Lexaloffle..

One of the best gameplay I've seen on PICO-8 plataform.

Very good game, it's fun,  i really enjoyed it, i loved it


Really nice art and controls quite well, but the "run around randomly looking for computers" isn't that compelling or interesting. Would also be nice if there were more sound effects (shooting and jumping).



add 1 or 2 checkpoint


missing one point

Bugs are difficult to hit because they don't always line up with your gun, and there's no way to hit them unless they're directly in your line of fire. I wish there were either more aiming options or more suicidal enemy AI.

Also think going with lives was a big mistake. I get that it's retro, but lives were always a frustrating artificial lengthening mechanism. It discouraged me from continuing when I got a game over and lost all my progress.

Love the music and visuals, though. Hope my feedback was helpful!

X Zero, at least in my opinion, definitely captures the simple enjoyment of old games. Just running, gunning, and doing the thing. I like that. The music isn't half bad, either. It's a bit repetitive after a while, but still has a nice sound it that makes me wiggle my gun to the beat. (Though not in public.) I'd wondered at one point why the gun was silent, but then I realized...I fire it constantly. So it's a fun AND smartly designed game.

Good job, dev.

Praise aside, I did notice on occasion that the game would speed up, sending me flying forward or quickly jumping around, often to my detriment. Not sure if this is on my end or the game.


Aunque el juego es muy bueno, me hubiera gustado tener mas variedad de enemigos y de escenarios, y tambien mas variedad musical. Sin embargo el arte y la musica me gustaron mucho, y me divertí. Bien hecho

Love it! Would definitely enjoy it more if I had a game pad. Good work.

I really like the nes-style graphics and the music! This def feels like a game that would have been on the nes!

Cool game!


this is awesome, gives me some old school Turrican vibes! great job, love it :D


one of the better Pico 8 games

Fantastic game! Finished it many times (my tip: keep pressing the shoot button), and I love the music too, playing it at times on my synths. Glad you posted it on, now I can buy it ;)

Thanks, I'm glad you enjoy it. Constant shooting is definitely the way to go. It's also a good idea to never rush forward.
