I wouldn't say I raged, but I did get frustrated with the cauldron from the level "be wheely careful", though I was okay with it during the "dungeon of defright". The fight with Neptuna however, I was surprised I was having a bit of an issue with avoidng his magic attack. I died many times to him.

Be free my platform! BE FREE!!!

Gonna say Be Wheely Careful, due to having done this level so many times because of the bonus level, just to get the gobbo I need to try and 100% the game

I forgot to say I passed lol
