The customization is nice and the stickers are pretty funny, i especially like the cat one.
game design wise,player's health recovery is too reliant on skill effects + 20s long CD which can lead to a passive playstyle of hiding until skill CD.(unless you play red bird and just kill everything)
white tiger skill's base damage is too low,and the bullet size upgrade is bugged on it and 2 upgrades of it makes the skill's bullets all vanish
unlike white tiger,Aoi dragon combined with the bullet bounce upgrade makes it viable
the homing upgrade also dont work with bullet count upgrade
the bullet bounce upgrade dont work with ring of bullet upgrade unless you buy a new bullet bounce upgrade
theres also a bug of being able to use the skill when picking new upgrades
the background also spins too fast imo
