It would be an ok enough platform shooter if it weren't for the lack of i-frames and the cheap difficulty that relies on screen crunch due to the sprites being too big, with blind jumps and enemies appearing out of nowhere to damage you and the combo of blind jump + the character's animation after falling from a very high place + acid floor + the lack of i-frames that makes you lose more than 80% of your HP for free, the levels are all pretty generic too and there are only two levels themes per world, so I'm not really missing anything by stopping in the middle, mainly when the game is longer than it should be, B.O.B. is a funny character at least, his goofy animations are the best part of the game and he's my top skin choice in Super Metroid Varia Randomizer (Which is what motivated me to finally give this game a try, by the way).
