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.


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.
