About Dev_Null's Tower

Dev_Null's Tower - about the game

"Dev_Null's Tower" is a vertical-scrolling action game where you climb a tower riddled with bugs.

You are this tower's playtester. The developer? A sarcastic AI named "Dev_Null." Send him "bug reports," and the stage will be modified in real time.

But your requests will always be granted with malicious intent.

AI Negotiation System

Whenever you die, get stuck, or just feel like complaining, you can send bug reports (complaints) to the AI via chat.

This game uses an LLM (Large Language Model), so you can negotiate freely in natural language.

Your requests will always be heard. However, the AI always delivers "another challenge" as a package deal. What side effects await? You'll just have to find out for yourself.

Bug Report Tickets

Negotiations require "Bug Report Tickets."

  • A limited number of tickets are issued per area

  • Once you run out, your only option is to reset

  • Do you save your tickets or aggressively spend them to reshape the stage? Strategy is key.

Real-Time Stage Modification

The AI's fixes cause the stage to change right before your eyes.

  • Adding or removing platforms

  • Repositioning enemies and traps

  • Adjusting physics parameters (gravity, wind)

Procedural Stage Generation

The AI procedurally generates parts of each stage. The stages change based on your past negotiation history and chat content. Your words shape the tower itself.

Dev_Null's Personality

> "Isn't it a bug in your skill?"

Dev_Null is a capable but temperamental craftsman-type developer AI. Sometimes sarcastic, sometimes humorous—it might depend on his mood that day.

Not impossible to beat. But you might not want to. Stages like that may be waiting for you.
