The Ruins have finally been conquered: Demo Incoming Yes, you read that right. And not just done , but DONE, DONE, DONE , as Rumi, Zoe and Mira would probably put it. Mechanics, content, story, menus, progression data, highscores, features, polish ... i...

#ruinsOfCalaworm final demo build will hit @itch.io servers later tonight. Overall, the game is a wrap! Yay! Here's the accompanying devLog entry where I am commemorating my achievement (I probably should do these more often - writing devLogs, not celebrating myself, that is๐Ÿค”).

Custom Difficulties are a WRAP!
In the end I went for a simple binary Unlock-Method, instead of a collection-based one. Wanted a fair challenge somewhere in between forcing you to beat the game, and just grinding it out.

Split-screen comparison meme showing the same person in two poses. Left side labeled 'OpenAI 2015: Profit - $0' shows person in casual green long-sleeve shirt with arms crossed. Right side labeled 'OpenAI 2025: Profit - $0,000,000,000' shows the same person in formal business attire (navy blazer and white shirt) with arms crossed, depicting how the company became more professional-looking while maintaining zero profitability.

10 years of OpenAI:

2015: $0 profit
2025: Still $0 profit (but in a blazer)
Lost ~$8B in 2025.
Projected $14B loss in 2026.

Deutsche Bank estimates $143B in negative cash flow before profitability.

But hey, at least they upgraded from the t-shirt. That's progress, right?

More Chokepoint-shenanigans ...
Foes no longer attack diagonally in or out of chokepoints. But they WILL retaliate, if you attack 1st! This probably comes with some emergent tactical ramifications you're free to exploit, but for now I don't see a massive problem.

'Ghost Walk' is a secret legacy mechanic from the original #Kalawaum game, that #ruinsOfCalaworm is based on. It was on and off during development; never really found a meaningful way to integrate it with the expanded mechanics - until now, that is.
Be very, very curious ... ๐Ÿ‘€

FYI:
Promised I'd be done with #ruinsOfCalaworm before "Winds of Winter" and "Star Citizen, and I'm happy to report that I'm on track. End of January still seems realistic.๐Ÿค—

Roadmap:
- Get it Golden
- Demo
- Trailer
- Doc for Editor
- Release

For a bit of distraction and variety during the development of โ€œLeaves Of Destiny,โ€ here's a preview of another project that uses the basics of my self-developed game engine.

#ruinsOfCalaworm has a dedicated setting for bonusXP.
Needed a fair method to apply percentage for single-digit values:
โ€ข Whenever XP is gained, add value to storage.
โ€ข As soon as quotient exceeds 1, release raw INT-chunk
โ€ข Calculated residue via MOD operation
โ€ข Set as new stored value

Part #8: Creating a new Endboss for "Tales of the Laser Knights"

Added some paintwork, and a new lightning weapon, electrocuting the player and slowing him down.

Here is a new trailer with updated GFX, heavily new cut, bringing more action and more endbosses ... even if not all graphics are final (will they ever be?)

I also hope to better support Steam auto-mini-trailer generation ๐Ÿ™„๐Ÿ‘ฝ
