Hey, thanks for the feedback!!!
I'll try to do a more interactive tutorial next time!
As for SFX, space does not carry sound! Just kidding, I didn't have time to do it better....
I did a HTML5 port! It is not perfect (Some lag on the background movement). I still prefer to play the executable version!
Also added some SFX as per your suggestion! Thanks!!! All feedback is highly appreciated!
I may develop it further if there is enough interest during the game jam. Some people, like you, really liked it, which made me very happy with the work done!
