Thanks for play my game.
Hmm. Originally, the idea is to expand the game time by simply repeating the rescue mission. Guess it may not work. But at least the difficulty problem seems fixed, so it's good. I will keep improving the float mechanic because it's quite the unique element for the game and i hope there is no need to cut it.
The bucket was supposedly just a "kick the bucket" punchline, but it blocks projectiles. Hence, in the latest version, i decided to expand its colldier size so that high-level player may use it as portable cover in final boss fight.
(Apart from Hell level, there is Reincarnation level)
