This is a really fun auto-battler style game! The use of hololive characters makes the characters recognizable and gives you a clean art style to work with. I kind of like how fast paced this ends up being - I think maybe a timer and a cooldown on how fast you regenerate points for your cards would add more complexity to the gameplay, but right now, slamming down cards nonstop feels really satisfying, and I think that kind of card game-play would make for an interesting full game if developed more! The only thing I'd suggest past the timer would be to adjust the angle of the camera a little bit so the player can tell how many cards they have out easier, right now they all sort of stack into one spot, turning the camera would let you spread them out on the Z axis
