This?
Yep, the game is located in Poki.com. It's not on itch.io yet, but it will be, soon. I've started playing that game last week.
I don't know where you got that from, but I'm not planning on an Itch release for Hop Warp since the web version is exclusive to Poki.
Wait, how come? Does that mean Hop Warp will only be available on Poki and not on any other website (like, CrazyGames, ArmorGames, Newgrounds, etc.)?
Correct
And in fact, does the same thing also go for Platform Countdown as well?
Yeah
One more thing to ask you: will Ledge Throw also be available on Poki and not on other websites (like Itch, CrazyGames, Newgrounds, etc)?
Yes, and you don't need to ask this for each Poki game.
Sorry, I was a bit curious, but I'll remember next time.
