Atomic Test (Legacy)
ATTENTION: This version is now LEGACY.
Based on community feedback, I have completely rebuilt the game from scratch. The new version features a massive engine refactor, physics-driven flow, and a much smoother progression system.

(I am keeping this page active so I don't break the save files for current players, but all future updates and support will happen on the new page).
Welcome to the Lab, Scientist.
Atomic Test is an addictive roguelike-incremental simulator where you manage the building blocks of matter. Master the delicate balance of physics-based action, strategic upgrades, and prestige systems in a high-stakes quantum environment.
This is a FREE DEMO. Experience the core loop of atomic experimentation and help us shape the future of the project!
Key Features:
- Experimental Runs: Every session is a new chance to optimize your fusion strategy and discover new elements.
- Incremental Progression: Merge light elements into heavy materials to skyrocket your Science production and unlock higher Tiers.
- Upgrades & Prestige: Accumulate scientific data to unlock powerful permanent buffs and reset for even greater rewards.
- Physics-Driven Chaos: Feel the impact of every collision in a dynamic field where mass and speed change everything.
Are you ready to trigger the perfect chain reaction?
Help us build the future of Atomic Test!
As an independent developer, your feedback is invaluable to me. This demo is just the beginning, and I want to hear your thoughts:
- Found a bug? Let me know in the comments below!
- Balance & Difficulty: Is the prestige system too slow? Are some atoms too hard to get?
- Feature Ideas: What "Quantum Spell" or element would you like to see next?

The Molecular Synthesis upgrade in the laboratory under "core infrastructure" does not seem to be working as stated.
Despite having upgraded it to max, and it reporting a 2:1 ratio for adding larger mass molecules i am being charged a 5:1 ratio for all of it.
Now merging beryllium seems to make the game hang; the two lithium ions just freeze there and everything stops moving. Aborting experiment does nothing.
Edit: This was after playing up to Boron then loading the game up again after the latest update. Wiping save data seems to solve the problem.
Thanks for the report! I've been trying to replicate this Beryllium hang on my end for the last few hours but haven't had 'luck' breaking it yet.
Could you help me investigate? If you can, please join r/atomictest so we can do a proper follow-up. I'd love to know:
Which browser are you using?
Did it happen exactly at the moment of impact or after some time?
If you open the developer console (F12), do you see any red error messages?
I want to kill this bug before moving to the next features.
almost 100% sure AI was used to develop most of the game
Thanks for playing and for taking the time to comment. I've been a professional programmer for 15 years; I use AI as an assistant for repetitive or simple tasks to be more efficient, but the core physics, atom logic, and game balance are all my own work.
glad ur honest its a great game im enjoying it!
Thanks a lot! If you find anything broken, let me know!
There should be an option for us to choose which containment field we want to use after we purchase the upgrade.
That way we can do experiments to more efficiently stack up atoms instead of going big and then having a major fall of on income and atom saving.
As far as I can tell the quantum skill tree upgrade "Molecular Friction" does not work.
I just purchased the upgrade and I am not getting any science when my particles collide with the walls.
This is frustrating since there is no way to redistribute the skills, so it is a completely wasted point.
Thanks for playing! I'm going to check that skill right away and I’ll also include a system to respec your skill points. I’m releasing v0.1.1 in a few days with several changes and fixes. If you find any other bugs, please report them; it’s really hard to test everything on my own. Thanks for the help!
The gameplay is quite frustrating, from the near-misses between atoms of the same tier to collisions between atoms of different tiers getting in the way of reactions, the inability to extend the duration of the experiment, the absurd RNG to get boron (and the even harsher grind to get carbon), the fact that it costs several non-hydrogen atoms to get even a single one in the field...
Hi! Thank you so much for this detailed feedback. This is exactly what I need to hear as I'm balancing the game for the full release.
I take your point about the collisions between different tiers being frustrating—I'll look into ways to make the reactions smoother. Also, I'll review the RNG and costs for Boron and Carbon, as it seems the difficulty curve is too steep right now.
My goal is to make the 'experiment' feel rewarding, not just a grind, so I'll definitely be tweaking these numbers in the next update. Thanks for playing long enough to reach those tiers and for helping me improve the game!
