I've played the original Boss Rush by TicLos, and I thought it was pretty solid. It's a nice little run back to some of the most iconic boss fights in the game. Definitely leaves a lot to be desired though, so not really a high enough rating for me.

Now with Boss Rush 2 however. Holy freaking improvements. This expands beyond the first level by 10x the mile. It's another "3" round Boss Rush with some other iconic boss fights, but here, there's a lot to explore from within the platformer before you actually fight the bosses. The bosses here compared to before have different mechanics specifically catered to them, and some can also carry once you actually beat the bosses. It is something in which I think the first Boss Rush kinda lacked, cause before it was all "go to this specific point and the attack will land," and really missed a lot of opportunities of doing something that's unique to them specifically.

I really enjoy this platformer. Has a lot to explore, really fun bosses, and also has an interesting story to offer. (Also, voice acting in a GD level. Really nice touch)
