The sun is running out of energy and the world needs your help to power a new one!

You collect power by LEFT-CLICKING the shards that break off from the Power Crystal! Once you collect enough power crystal shards, you can buy upgrades until you unlock the final upgrade, launching the new sun! New upgrades are unlocked once you buy at least 5 of the previous upgrade.

Lightbulb Program is a small idle, clicker game made for Kenney Jam 2025. This is my first game jam ever and I'm pretty happy with what I was able to make in such a short amount of time. A little boring maybe but I think it's charming!

As this was made in a short amount of time, bugs are to be expected.

The following Kenney assets were used:

Game Music Loop 9 by XtremeFreddy was used for the background music.

i didnt want the sun i wanted a buffer miner 

Very good clicking/idle game, well done! (I'm writing this comment while my little slaves drones are gathering more POWER)

I'm impressed by this game's engine to handle big numbers 

This was fun btw. ;-)

Very cute and very addicting! Congratulations on making this! :)

It feels very slow at the beginning, but as soon as crystal efficiency is unlocked, it suddenly becomes fast. You will certainly find better math there :)

Also connected to math: why not use whole numbers only? Probably is personal taste, but my brain did not approve of the decimals from the cost increase. With whole numbers you can also easily fix the digits jumping around.

But as others pointed out already: it has a nice atmosphere and i really enjoyed the shards flying around and not just clicking on one point the whole time :)

A very good idle game! I love how you use only the pre-made assets and are able to craft a game with such a good atmosphere. The lightning is fantastic, too.


I have a few suggestions for the game too, just a few minor details:

1. For me, it can be a bit boring in the middle, before I unlock the crystal efficiency. Because the next level up isn't visible, it can feel like I'm not progressing at all.

2. The music doesn't continue after it has finished.

3. At the start, i'm quite confused on what to do, maybe add an in-game tutorial? (A simple mouse hovering toward it will be fine.) [I'm not the type to read the description unless neccessary, I want to experience the game as a whole.]

That's all! Pretty solid game nonetheless. 7.5/10!

Finished it whole. Quite entertaining :). Managed to gain number so huge it was larger than whole screen thanks to shard efficiency. 

Very cool! I wish we could have multiple miners in the beginning. I liked when the blocks stacked each other even though it was probably unintended!

This is so adorable i love this
