This game doesn't play. I just get a black screen.1 found this helpful
Accelerator Operator is a really interesting little strategy game because it takes something that sounds complicated and turns it into a simple puzzle about making money from chain reactions. I am basically running a particle accelerator and placing different materials in the path of high speed neutrons. When the neutrons hit the right materials, they split into more neutrons, which can then create even bigger reactions. I like how easy the main idea is to understand while still giving me plenty to think about once I start trying to build better reactions. The chain reactions are easily the best part for me. I have to place the materials carefully because different types behave in different ways. Some materials create more neutrons, while others can multiply or redirect them, and some increase the money I earn from the neutrons. This means I am not just trying to create the biggest explosion I can. I am trying to work out how the different materials can interact so that the reaction keeps growing and eventually gives me enough money to reach the target. I also liked the roguelike structure. I get perks as I progress, and the combinations can change how I approach each run. There …
Cute tiny free game. Wish there was an endless or sandbox mode or some way to let the reactions get truly wild.
fun little neat game. chain reactions are fun!
Pros: It's a fun concept The gameplay feels unique, as in it doesn't come across as derivetive to me. Not time consuming. Balls :Q___ Cons: Windowed mode no worky- could be user error (no idea). The UI needs some big love. Overall: You oughta buy it. Do it for the balls.
The game seemed very hard but it's super easy and even relaxing ! And i love the possibility to start with any type of "atoms" it really adds up to the diversity, Great game !
