I have never played this mod before.
I'll give it a try, even though this statement
eventually I hate every single mod that I make.
makes me kind of afraid.
EDIT:OK, I played it, and I'm going as far as saying this is a hidden gem, I'm dead serious.
This mod was made using a lot of custom mechanics, weapons, and I believe even enemies. From what I can tell, this is the result of multiple scrapped mods, BUT it is more than that, trust me.
The story was pretty interesting overall(If you don't like it you can also skip cutscenes...I think? It didn't work for me.) and believe it or not the dialogue is not that bad, which is an achievement in itself a Cave Story mod(although, I did find some typos)
The levels are fun, even though the part towards the end was a little unforgiving for me since after I died I got back to a checkpoint that was far away.
I found the new weapon to be fun to use, however I do think that this is a good example where it would have been better if the weapon didn't have levels, but that's just a thing of mine.
Does it have anything else that is wrong with it? Well, of course it does, for example there was a part where you were supposed to guide Quote but he was moving at the same time, so I wasn't really controlling him...I'll admit that was pretty bad, but guess what, YOU CAN SKIP THAT, hell yeah.
So, would I recommend it?
Listen, I said this was a hidden gem, but we're still talking about a Cave Story mod, so my actual hint is: give it a try, and then you tell me if you thought the mechanics that allows you to open doors in midair were cool or not.
