This was one of the first games I had ever played as a kid, and I absolutely struggled with it back then, now probably like 15-16 years after I first ever tried to play it, I finally came back to do what child me could not.
And, honestly I really enjoyed the game. I like how FLUDD works, and a lot of the levels were fun to do. I noticed I had a lot of difficulty in the beginning as I was trying to figure out Mario's movement, but once I figured it out, the levels became a lot easier. Though even then, I feel like some levels were rather annoying. The casino one especially, sometimes the panels seemed to just behave incorrectly for some unknown reason. But the water and paint mechanics aside from a select few levels are really fun, and it might just be the powerwash fan in me, but I love being able to clean away all of the paint off of things.
Though the one thing I can say for certain is that there is no way I'll ever willingly 100% this game. If I tried to, I can predict that I would hate this game, and I don't want to hate it.
Even through the frustrations I had with it, I'm glad I finally got around to fully beating this game though. It was long overdue.
