Thank you so much for the feedback and i'm really happy you like my game :)
Yeah I also notice there is a bug on the double jump sometimes. Thank you for noticing that, im gonna fix it.
And yeah I also thought your game is same as mine but your game is the really unique one and enjoyable to play too! For the SFX and music, im still learning on how to create them. Gonna practice more. Thanks again so much! Cheers man.
