Me and a couple of friends of mine finished the game again after hearing what rework to the levels were done and we found the game to be WAY too easy now compared to before where it felt completely fine. I'm not looking to go to into extreme detail here, I think the best way I can put it was all the level layouts before the BETA changes on level FUN were finished.
Level FUN
-The platforming before the maze no longer has the lights turn off for some reason AND platforming is way too lenient with the current 2 platform then pit pattern (1 & 1 felt fine)
-The maze horn giving the exit location needs to go back to 5 coins (again this is for a classic or "hard" mode)
-3 mazes should be the win condition over 2
Pipe Rooms
-The times over the entrances should all be different, not sure if it was specifically how the level generated but they were all just hit the button, display the same time for each of the rooms then leave which is frankly a bit boring and easy to brute force
Power Station Level
-I much prefer the 3 floor layout and one central station, I found that much more fun (new layout is not bad)
Pool Rooms
-The only thing I noticed was that certain walls were missing and I don't know if this was intention to find the stairway easier or not since theres already windows to see out from
-People already mentioned addition of an entity but there needs to be a way to get it to back off from the players or some kind of hiding spots
