Click anywhere in the grey area to detonate your Green Atom. Any Red Atoms coming in contact will react and expand. The more Atoms you expand the better you'll score!

But be warned Red Atoms only have a limited half-life, so act fast before they disappear!

Feels... a bit boring. The upgrades don't seem to do very much individually, so you don't get a real sense of strategy with them, overall the game feels a bit too random(for instance, the difference between 2 stars and 3 stars can be a single atom bouncing nearly vertically somewhere close to an edge), and the levels start feeling samey pretty quickly(and in fact, several levels are identical save for the 1 and 2 star targets). Condensing the upgrades(so each time you buy an upgrade, it makes a noticeable difference) and adding some variation to the levels beyond the number of atoms(even different colours for different levels would help give some sense of advancement, I think, but adding things like obstacles or one-way walls would be great) would make this a pretty good game.

To me, excellent game!
Just needed to finish it!
Nice graphs, running, easy but cool idea, great game-achievement-medals dynamic!

Thank you! I'm glad you enjoyed it! <3

nice music and original idea, despite not being realistic.

blit-blat responds:

Thanks! The music is by epitaph64. You should check out they're other tracks over in the Audio Portal! :)

This was amazing fun! My bf and I played over until we got 3 stars on each level. (y) It was really captivating and the music was calming (I got really frustrated at times lol). Excellent job with this. :)

blit-blat responds:

The music was done by epitaph64. Check him out:


I'm glad you both liked it! Who was the better player though, you or your bf? Maybe I should make a battle mode where you guys could compete! :P

I love it! Until I didn't have all the medals I couldn't stop playing!

blit-blat responds:

Woop woop! I love that you love it! Of course if there's anything you'd like to see in Atomic 2 let me know!
