This was all-around decently fun, but the "Bowser in a Starfield" bowser fight was... not it, to put it lightly.
First, the arena design was pretty bad - there's a hole on the spawning platform which you can fall through and die, there's a fire thing on the middle platform which can light you on fire and thus basically guarantee that you run off the edge of the platform, and there are only bombs on one side of the actual boss arena, which is annoying in it's own right and also the source of another issue I'll get to later.
Second, whenever you *miss* a throw, Bowser lands either on one of the smaller platforms, or on the other side of the arena from the bombs - and your throw doesn't go far enough to toss him at the bombs from there, so you must either slowly lure him over to the other side of the arena or make a few smaller throws to get him to a point where you can actually hit the bombs.
Third, Bowser is able to walk off the edge if you're on a different platform from him, which will softlock the fight and force a retry, which is very irritating. Additionally, he can also fall off the edge of the arena after hitting a bomb and landing back on the arena, which I believe causes the hit to not count, forcing you to do the process all over again with one less bomb to choose from.
All-around, this was a VERY sour spot in an otherwise pretty fun rom hack to play with two of my friends - and I hope this feedback can be used to revamp the arena design.
