Subject: Feedback on Jump Animation for Lioren Lael
"Hi! Thanks for the reply, but there is a misunderstanding.
The animations currently in the pack (Air_Jump, etc.) look like levitation or flying, not a standard ground jump. The character just 'floats up' without a proper push-off. Also, the landing is too long — he stays in a sitting position for several frames before getting up, which makes the controls feel laggy.
To make the character feel 'snappy' in a platformer, we really need a simple 3-phase Ground Jump:
Anticipation/Pre-jump: 1-2 frames of crouching before the leap.
Fast Launch: A quick upward movement without flips or 'iron man' poses.
Soft Landing: A quick 1-2 frame landing that allows the player to start running immediately.
The current 'Air' animations are great for special moves, but the game feels broken without a basic, functional jump. Could you please consider adding a simple, fast jump set?"
