i'm playing on itch but i gave me an antipiracy screen


Hi Pocketfruit, 

My name is Antonia Gates, I manage the games at CoolmathGames.com. I really enjoyed playing Molecules! I think it would be a great fit on our site. 

I’m writing to ask if the game is available for non-exclusive licensing. Our licenses are totally non-exclusive, so you would maintain all of the IP rights and could continue to develop and distribute the game however you’d like to. If you're interested, please email me at agates@coolmath.com.

Amazing Game!

This game certainly has something too it, and i can see you put some work into it. The controls feel pretty clunky however, and I don't feel like it would really be worth my dosh. Good work all the same.

Hey, just letting you know your anti-piracy system tells me to play it on pocketfruit.itch.io.........even though I'm using the official Itch.io client app for windows anyhow I don't know how you could go about fixing it since I don't know anything about Pico development anyhow I enjoy the games you make

Thanks - will look into it.


I made a 100% completion video for your game.

watched on 2x speed and now my eyes hurt. Well done!!


Really fun idea and well executed! I'm suprised i didn't know browser games worked on phones i feel I've been missing out!


It looks awesome! Funny simple concept and really entertaining. I'd personally like a level selector, since I had to leave the game at level 30 and know I can't bring myself to do that all over again...
It also felt like the levels dragged on a bit long for me. Like, it looks cool, but some feel unnecesary.


Really good! To say that the visuals are awesome would be an understatement. I haven't even heard the sound yet (just played it muted), but I bet it's awesome too. All in all an amazing games, saving this for sure.
