"Oh it's like Kirby it'd be so cute if they could share hp with a-" OH WAIT THEY DO!!
This was super fun! Playing in-browser reminded me of a flash game platformer; made me feel very nostalgic :)
The gameplay is great, given characters' abilities to fly the infinite jumps make sense, and with little details such as recoil after shooting a bullet I can tell this is a well-polished game. One thing I wish there was more of was story--Rumia is causing trouble, but we don't know why, nor do we see evidence of it in the game (would she have made everything dark or something?). Other than that, super fun game that I enjoyed playing (repeatedly until I could beat the boss XD)
