To elaborate on what can get you in this thing:

*ferdoido himself - will constantly chase you & with every passing tune of the Kendrick Lamar scream, he will grow bigger, faster & increase the tempo of his sound (which, in term, will make his actions go by quicker)

*the pool in the middle is also a noteworthy obstacle - takes up a lot of space & for the record: the coins necessary for collecting can spawn in there, forcing you to wait out until they'll be in a hopefully-better spot

*there are also fake coins - they're a shade of green &, if clicked on... I think you know

*a J holding a bag of Wega may rush you down from the corners, sometimes spawning clones of itself (ooh!)

*denying Luigi also spawn from corners & his chase, albeit slow, is endless until he gets you. Due to it being tax season, he will take away one of your vital coins in posession. He can also spawn clones of himself (ooh!)

*a turret will spawn in the pool after some time. It will constantly shoot out orange bullets at a very fast pace

-not a gameplay mechanic, but worth elaborating on: cheesing is not very viable for this game project. You can do it, but Fredoido (& everyone else that can) will game over your ass if he touches the edge of the screen

And yes: I playtested this prior to release... it was as difficult as you think
