Open Source challenge results from Gamedev.js Jam 2023

This is a guest post by GitHub Star, @end3r. Andrzej Mazur is a web game developer and technical evangelist, founder of the Enclave Games indie studio, creator of the js13kGames competition, and builder of the Gamedev.js community.

The Gamedev.js community started around the year 2012, but mostly revolved around local meetups at the beginning. First international attempts were made with the global Gamedev.js Weekly newsletter in 2014, yet we had to wait until 2020 for the first Gamedev.js Jam to happen. The third edition held in 2022 was the first to ask the developers to (optionally) provide the sources of their games. That turned out as a great success—out of 95 submitted games, 27 provided their source code on GitHub.

Fast forward twelve months to April this year and the participants of Gamedev.js Jam 2023 submitted 201 games, out of which 91 joined the official Open Source challenge and provided their sources on GitHub. Below is the best 13 selected by the dedicated experts, Michelle Mannering, Ewa Mazur, and Ania Kubów:

2. Time Rush

Play Source

“Really cool, complete and very polished platform game. Music makes it dynamic, controls work fantastic. I love all the little details like moving background, character particles, time shaking, when it’s almost run out. Everything is just perfect. Graphics complete the game mood – fantastic job.” – Ewa Mazur

3. Latency

“This game had cute graphics and a simple game play which allowed me to start playing instantly. But do not be deceived, passing to the next level is harder than it looks!” – Ania Kubów

7. Chrono Robot

“Having to time your movements in order to be able to work with them in the ‘future’ is always a fun spin in games. The dev leaderboard is also a nice touch.”  – Ania Kubów

7. Time Saver

Play Source

Unity C#

“It was very hard for me to play the game, but still I love the idea and the look of it.

Great job” – Ewa Mazur

9. Chrono Guards

Play Source

TypeScript

“Easy to play, really nice game, yet the idea of it is very well fitting to the game jam theme. I like how the graphics make it a little bit magical. Maybe I would think of some more delicate details, like some particles, lightning or something like this, so the mood of the game would be even more magical. but it’s just details – the game is very cool right now.” – Ewa Mazur

9. Toki

Play Source

Typescript

“The movements to this game were very smooth and pleasant to play. There were also unique game tools at the user’s disposal on top of the normal ‘jump’ and ‘shoot’.” – Ania Kubów

11. The Bow Fighters

“What touched my heart was that the game looked really nice. It was a little bit hard for me to discover how to play (I’m not reading the instructions), but then the game was really good.” – Ewa Mazur

12. Time Warp

Play Source

Unity C#

“In this game the added complexity of traveling in time added many layers to this game. I enjoy when a game looks simple and minimalistic, but in reality is a lot more complex, whilst also remaining easy to play. This game did just that.” –Ania Kubów

13. Birds!

Play Source

Phaser Typescript

“Fun, great and creative implementation of the theme. Consistent graphics. Clever, addictive. A convincing story.” – Ewa Mazur
