Short
Interesting aesthetics but <some motions> does NOT feel right with aesthetics.
Long
Game start is little hard, if I am not PRO little more forgiveness please.
Small cards looks like obstacles (looks very similar to cards), if you are not used to it.
Add <little camera movement, scale, rotate> ... to gain non static view/motion (now game feels static <low animations>).
Game interpolations are made mostly with lerp() function ?
(I call this function wood ... the wooden function).
Try out this link and try out to give different feelings: https://easings.net
or create <custom baked curves> or impact interpolation rules.
I think <slow impact> on death (low speed fade) killed potential.
Example with stronger <onDeath() impact>:
1 ... camera shake (or come more complex camera movement),
2 ... fast impact fade/flicker based on interpolation/tween (shorter time)
3 ... backed with sound (try with simple BAM)
