Would give you some slack on the game mechanics if you were mixing things up but it seems like you literally just wanted to remake Flappy bird (which is fine) but my point is that the game is too easy, it isn’t even a challenge, from the physics of the bullet to the variation of the tubes.
Other things to point out:
-You can see where the tubes spawn
-When you customize the sprite, it doesn’t even change it
Played your other game, pretty much the same and has some flaws but we are all getting there, keep it up man but never delete your old work, its always nice to see how far you have progressed.
