Shelled Shinobi

Alternate between classic platforming and controlling a fast sliding shell.


Keyboard / Gamepad:
Move: Left, Right arrow keys / Left joystick or D-Pad (p8/bin).
Jump*: Z or C / 🅾️.
Shell*: X or V / ❎.
Pause, Options: P or Enter / Start (p8/bin) or Back (web).

*Can be swapped in the pause menu.


Depending on your device and browser, the game may stutter in the browser version. In that case, please import this cart to PICO-8 or launch it from SPLORE.

You can also download the game on itch.io: https://noppa.itch.io/shelled-shinobi.

It's currently also possible to lower the framerate in code by changing the value of 'fps_60' in '_init()' (could be useful for e.g. RPi0 users?).



  • Fixed final room missing boundary
  • Fixed a displaced pixel (and added another pixel :P) in the title graphics
  • Replaced the 30 FPS build with the 60 FPS one in itch.io
  • Updated some details in this post (in "Controls", "Versions")


  • Added copy protection
  • Added credits to the title screen
  • Removed thanks from code comments to save on characters
  • Misc. minor graphical changes
  • Removed some unused variables and other minor code cleanup

@waynaul, @ChakAttack, @NerdyTeachers, @Mikesta
Thank you so much!

Edit: I gotta say thanks once more @NerdyTeachers, this game wouldn't have happened without your inspiring tutorial! It was exactly what I needed at that moment.

Love this. Really fun to play. Congrats on the release :)

P#78665 2020-06-29 14:25

So glad our tutorial helped that much! You took it beyond what we imagined anyone would. As we update our site, we will certainly be featuring this game as an example.

Starred and Favorited.

@Meep Wow I knew you'd be fast, but damn! I'm really glad you like it.

@tororoxu and @bigjus Thank you, thanks for playing and commenting!

@Gruber Yay awesome that you played it, thank you! Thanks for making the PICO-8 Tunes available, hope I didn't butcher the beautiful tunes too badly.

@NerdyTeachers Awesome, I'd be honored!

P#78680 2020-06-29 20:49

THIS IS AWESOME! Guess it will become my favourite, I painted many graffiti myself :D

P#78685 2020-06-30 00:28

Whoa, this is amazing. Fantastic work! The polish is super high on this. Wow...

@noppa It sounds great. I really like hearing other people remix and rearrange those tunes.

@Yesyoor Thanks, that's great! I'm not terribly good at handling a spray can myself, but I have some graffiti artist friends. Glad if you approve the use of graffiti in the theme :)

@MBoffin Thanks so much for the kind words! And thank you for your teaching and resources!
I was a bit on the fence if I should ping you all by tagging in the description or not, but now I'm glad I did! :D

Sorry, didn't know updating the post / cart would bump the thread. Hopefully at least it didn't ping the previously tagged folks again! D: In the future I'll try to keep it to major updates, if any.

(Edit: I mean the cart is finished and released, so no major updates are to be expected. Some very minor graphics tweaks might still happen, and I'll fix any major bugs, if such appear. Please don't hesitate to leave feedback :D)

P#78761 2020-07-01 17:51 ( Edited 2020-07-04 21:05)

No worries. It only pings people if you newly use their @ tag. Just updating the cart won't do it. It just bumps the thread to the top. (Which is fine too.)

P#78762 2020-07-01 18:10

I'd happily play another 9-10 sequels to this.

Edit: I tried to include shots of my time in my post, but apparently you can't have spaces in the filename? Let's try again:

P#79091 2020-07-09 11:20 ( Edited 2020-07-09 20:14)

This is awesome, love the game
