Interesting and fun gameplay. I don't know if the boss health get scaled with more player. But when alone it feels too high. Not made it harder just too high. just my opinion of course. That aside, Good work!
well there are some mechanics that contributs to a lot of damage, for example you using the star tool to dash/ram into enemies like beyblad and the extra burst damage you get every 10 hits ( which scales up the bigger your combo gets )
