Hey, pretty tight platformer! I'd like to give the programmers the benefit of the doubt that the blue field around the level was meant to be a big collision zone that just didn't work because jumping out there let me skip parts of the level sometimes. Being able to straight up jump past the exit door and fall down into the pit irked me a bit
Audio balance could use a bit of work just because the music was a bit quiet and the firing sound started becoming tedious in the boss battle.
Art and animations check out as well, couldn't tell if there was supposed to be some text at the end, saw something for a sec and it blipped away.
There's a pretty nasty safezone in the boss battle though, its sorta on the platforms near the entrance.
