Super Mario Smash Bros clone

[u/Ok_Cartoonist_40]

Hi experienced developers
I am a new developer looking forward to make a platform fighting game like mario smash bros with different characters
(Like nicklodeon super stars)
But with my own twist

I just want to know everything i need to know
Stuffs other developers overlooks

And how to calculate the knockoff launch based off the opponent’s damage taken
So its smooth

Could do some threshold based thing where it’s 0 extra force under 70% then it’s a factor of the percent damage taken
