Okay I'll start off positive cause i don't want to be destructive. First of all i think it's really cool that you made this game in Scratch, you don't see that too often on Newgrounds so i think that's really cool! Also when playing the game i can at least kind of see what you where envisioning cause it's kind of like an arcade game almost and that's cool!
But now I'm going to give some criticisms for it. First of all i kind of figured out how to play the game after reading reviews of it, and the description. But initially when i got on i had no idea what i was doing. I was a bit confused when i realized you could move past the pink walls. i figured out why i could when reading the description but initially i thought i had instantly broken the game
It would've been nice if there was a tutorial mode explaining the gameplay, especially given how simple it is
If you expanded on this game it would've been cool if what you set up was an arcade mode, and there where levels in it with pre set pink walls, or maybe even boss fights some how. It would also be cool if maybe there where power ups. Like maybe there could be a power up that would heal you for a couple of seconds
If you ever make any more games in the future it might also be helpful if you had someone play test it, so that if they end up confused you can understand why and make improvement's that way
I'm also leaving these criticisms more so as different ideas for if you end up making more games in the future, cause i doubt you'd change much in this game
Plus i still think it's really cool that you made this, and I'd hope to see more in the future. Have a nice day or night
