First of all, the fact that you decided to demake your own game is admirable, but the fact that this is also a remake makes this a really special experience and shows your growth as a dev.
The added verticality and downward momentum mechanic makes the game more engaging than it's original. Having proper difficulty curve act as a tutorial of sorts because players won't have to worry about the moving trampoline.
The presentation is also improved. The even thinner ball emphasize the downward velocity. The new design of the blocks helps conserve screen real estate. The shaking effect of the blocks is back and I loved how the blocks eventually overlap with each other.
One negative I found is that the high score system is pointless. Players can "die" to reset their height and they shouldn't be punished for using this useful interaction. This didn't affect my enjoyment, I just ignored the high score entirely.
I sincerely hope you will have a bright future moving forward, 10/10.
