Great game but I have some problems – Looty Dungeon Review

The game is fun and I have had ran into no bugs so far but my problems with the game are area spawn for example there's a area were there is only one way to get out and it's at the start of the room and enemies clog that one way and if you are not playing a high damage character the floor will collapse and you'll die and the last thing is the secret characters the only thing I want is a hint cause I dedicated a whole day trying to unlock these characters and have only gotten two out of pure luck I like how you can't buy them but I would only ask if you may add a hint to help us on the right path to unlocking these characters thanks for reading!!!
