Oh, dude... this is... outstanding! Best gbjam 5 game i've played so far! :D

The game feels good and looks good. Wall jump makes exploration great.

Loved this cute game. Loved the hardcore version even more!

Although it is a very basic shooter, it seems polished. Controls are solid. Nice work!

I wish I could stay a little more in this world. The characters are wonderful, and I wish I could get to know them better.

I liked the wall jumped and how it is used to explore the game world, but sometimes I can go back after wall jump, and sometimes I can't.

Overall, a pretty cool experience! Great job!

A ninja themed, Fantasy Zone like game. Like it!

Beautiful sprites. I'm curious to seehow it will evolve (both in graphics and sound). Great work!

Simple, beautiful, challenging, addictive. Love it!

(Reposting because I reversed the Z and X buttons in the instructions before... shame on me :v)

Instructions: Z key to jump. Jump over the Fungi a certain number of times to stun them. While they are stunned, press X to give them a Biscoin (if you have at least one) and you will make him Chawie's friend! After that, press up to talk to them.

(and thanks to the people giving their support!)

Hello everyone!

This week I was looking on how I could improve the music. Then I thought to jump from the 8-bit sound of early demos to the 16-bit consoles sound. I spent a lot of time looking for good audio plugins that emulate the YM2612 sound. This is the Sega Genesis sound chip.

This is the Chaw Town theme, 8-bit NES style:

Now, it sounds like this:

What do you think? This is not the final version, but it makes me feel excited to make the game!

That's all for now. Thank you!

Hello everyone!

Today I'm going to do something I should have done before. After all, what Chawie's Quest all about?


Chawie's Quest tells the story of a small member of the Chaw race. Chawie's world, Camandu, is peaceful and only few conflicts are registered in it's history. The last one, The Jay-Chaw war, was resolved when the legendary Chaw Chawollus came witth the ultimate solution to estabilish peace in Camandu: a Chawcake so tasty that it calms down the heart of the most troubled soul. Since then, Jays and Chaws are best friends, and every people developed their own Chawcake recipes for communication and peaceful negotiations.

After centuries without conflicts, everyone got used to absolute peace in Camandu. However, an alien is invading the minds of some people. The alien's objectives are unclear. All that is clear is that trouble is affecting Camandu. Chaws are suddenly getting sick. Fungi are getting aggressive. Chawie, the youngest Chaw, is tasked to retrieve seeds from the Millenium Flower. It only grows in the core of the Mystic Garden. It's seeds, people say, can cure any illness. But this little quest will become one that will extend to the entire world of Camandu...

The game

The game will consist of platform sections. During the quest, Chawie learns abilities that helps her traverse increasingly complex obstacles. Along the way, Chawie will meet some mean people. She will use some little violence to stun them, then she feeds them until they get friendly. Once they become friends, they can give tips or items or do some other thing they can do to help Chawie.

Weekly Report

Right after publishing the first entry in the devlog, I started to make the game logo. It is on the top of this post. Then, something unexpected came: the demo is painstakingly slow on some machines. I passed most time this week trying to remedy this. I uploaded a new version on, but it is still not perfect. I will make optimizations later. Now, I will focus on making the game, remaking and expanding the first area, and improving the basic mechanics.

A full week has not passed since the last entry, and I did not make much. I'll try to update the devlog every weekend.

That is all for now. Thank you!

Thank you!

I fell in love with the DB palettes the first time I saw them.

Yes, a macOS version is in the plans.

Hello everyone!

I'm starting the Chawie's Quest Devlog here. I'll submits updates here, but also on Chawie's Facebook page and on her own dedicated devlog. I'll try to update all at once. Also, check the page on, where you can download the demo.

Chawie's Quest began on GBJam 5, and since then I've been trying to color everything. From Game Boy's 4 colors to the DB32's 32 colors. Some sprites have changed as well.


I'll try to update the devlogs once each week.

See you all later!

Little updates for Chawie's.

Basically, the levels are the same from the GB Jam version. A few changes:

  • Chawie starts with 5 hearts, instead of 3.
  • Checkpoints! If Chawie dies, you can restart the game from the beginning of the last map visited.
  • Enemies can throw hearts (refill 1 heart).
  • Friendly enemies give 2 hearts if Chawie has only one.
  • Button tips at the game's beginning. The first enemy throws some popups showing how to make it friendly.
  • Some sfx redone.
  • Biscoins renamed to Chawcakes. It is cuter and implies less capitalism (more gluttony, though).

I hope that with those changes, more people can reach the "ending"!

Hey, hello! I made the soundtrack.

I'm gonna make the music less harsh to the ears during gameplay. Perhaps I will remake the entire soundtrack. I used only square and triangle waves, and those made the sound really grating.

Also, thank you for your feedback!

Hello everyone.

I made this game for GBJAM 5. I did everything - programming, visuals, audio.

Would you kindly give your opinions about the game? Much appreciated! :D

Instructions:Instructions: Z key to jump. Jump over the Fungi a certain number of times to stun them. While they are stunned, press X to give them a Biscoin (if you have at least one) and you will make him Chawie's friend, and then you can talk to them.

How to get biscoins: You can get the first one in the town. Sometimes, the enemy will release a biscoin when he gets stunned.
