Atomic Test: Incremental
Master the Ultimate Chain Reaction
Atomic Test is a high-precision incremental game where nuclear physics meets strategic optimization. You aren't just watching numbers go up; you are the engineer in charge of a continuous atomic flow. From the first Hydrogen atom to complex fusion reactions, every decision matters.


Why Atomic Test?
- Physics-Driven Satisfaction: Energy farming isn't just a counter—it's a tactile experience. The way elements interact and collide makes every gain feel earned and visually rewarding.
- Skill-Based Progression: Unlike idle games where you just wait, here your ability to manage instability accelerates your growth. Optimize the flow and master the chaos.
- Seamless Single-Run Flow: We’ve removed the clunky barriers of the past. Experience a fluid journey where the prestige system is a tactical choice integrated directly into the gameplay loop.
- Organic Evolution: Thanks to the physics-based core, your path to power evolves in its own unique way. No two players will optimize their reaction exactly the same way.
- Purposeful Automation: Unlock technology to delegate mechanical tasks and focus on high-level strategy as you push toward Critical Mass.


[Developer’s Note]
My intention with Atomic Test is to step away from pre-established formulas. Instead of replicating mechanics you’ve already seen in other games, I’m experimenting with a "single-run" flow and physics-based dynamics that challenge how you optimize progress.
I want energy farming to be a unique, tactile satisfaction where the behavior of the elements allows each playthrough to evolve organically. This is a living project that evolves with your feedback; my goal isn't just to make another game, but one that feels genuinely new in your library.

I had reached titanium, but I believe some of my nuclei were deleted when I fissioned too hard with 4 fissioners, rest lasers. So now I am at 1 Sodium, 1 Cloride, and 1 Potassium, which does not get me nearly as far
I like the concept, but as it is now the maximum upgrades feel a bit rewarding, and I have issues with using the on click gravitational pull (might be only visually that there is no pulsing, but it also feels very weak)
Also, it flashes the between the spanish and english words for how many eV I need to upgrade the nodes.
A very interesting concept. The beginning may seem a bit slow, but at one point the game really speeds up.
Completed the current version in 1.5 hours.
Glad you liked the concept! 1.5 hours is a solid run for the current state. I'm actually working on smoothing out that early game right now so it doesn't feel as slow. Comments like yours really give me the energy to keep innovating, so thanks for playing
This is satisfying to look at, the progression feels a bit rough and in dire need of testing, so hoping to come back next month to lots of improvement
Thanks for the feedback! Balancing is tough—every time I add something new, everything shifts. It’s like moving an image in Word 2007; I’m just trying to keep it from breaking while adding cool new features! Stay tuned for v0.3.0.
Very cool game, I like it!
Nice game. I do think early progression is a little tedious though, especially with all the clicking and dragging required. Some mouse related upgrades could help, like increased click area, stronger attraction, maybe even a right click to repel.
Thanks for playing! You're right about the early game; I'm working on making the progression smoother.
Just a heads-up: Right-click already repels, and the Spacebar works just like the left-click to attract/split. Also, the Prestige system unlocks 8 manual upgrades (click area, multi-fission, etc.) and an Auto-click Catalyst. Hope this helps you push forward!
Oh my god it never occurred to me to actually try right clicking. Good to know. Having manual upgrades be locked behind prestige seems a bit counter intuitive but if you made progression smoother it'd be completely fine I think.
