Rocket Bytes is  a A 1-bit precision rocket flying reverse platformer for Playdate where you control a group of rockets who need to  collect energy and bring it back to their ship (a bigger rocket) so they can fly it safely back to their mothership  (an even bigger rocket). 

Rockets look in the direction the crank is facing but are only propelled in that direction when you press up.  See how you can use this to bring them safely through obstacles to the ship.

  • 360° crank ACTION™️®©
  • Bangin’ OST
  • iPod mode (lets you play music) you can speed up the music in it and I find that entertaining :)

Seems cool, I wish it could be played without the crank tho


This game is so difficult it’s hard to get into! It would be nice if the gravity wasn’t quite so strong to make it easier to hover. Dying within a few seconds over and over again is just demoralising!

Sorry to hear that. Levels can actually have custom gravity values now so if you really wanted you could change the gravity in the level files haha. Sorry the game was hard to get into but while I am content with the main game’s levels I hope some more appealing user levels come out in the future for you!

I feel similarly, that the gravity makes this game QUITE challenging.  Ha-ha!

 @possiblyAxolotl , how does one go about adjusting the gravity, as you were mentioning in the reply above?

it’s not super straightforward but each level is stored in a JSON file so if you were to go into the game’s “data” folder where the levels are stored you could add the line

"grav" : (your gravity here),

and it would change the gravity. Default gravity is 0.2 so 0.1 would be half gravity, the rest is pretty self-explanatory


Love the game! Could you allow the B button to activate boost as well? It is much more comfortable for me to hit B when cranking, rather than A or UP.


just uploaded a new build, now any button works!


Paid $0.00 at first because wanted to try before buy.. after playing i came back and paid $3.00, definitely worth it and a fun challenge using the crank. Great work!

Thank you :D


This Celeste-like is a better game than most of the season one games!! I love this game so much. It controls like a dream (thank god because its pretty difficult), its just forgiving enough with how quickly you respawn and how it allows you to keep energy cells on deaths. Great soundtrack too. I give this game 5 stars, 5 rocket ships.

Thank you! I’m glad you liked it! I’m glad it felt difficult but still fairly forgiving as that’s what i had hoped for (I was worried it would just be too hard haha)





Wow this looks awesome! I'm excited to try it :)

Thank you! I can’t wait for everyone to try it either
