Quite good leveling game , but i have no idea how to level up. l collected few souls with the Lvl.1 wizard and then got kicked out of it when i touched level 30 ghost.
The game really likes level 5 wizards, i've only seen 1 level 1 wozard and 1 level 30 wizard.
About thee movement: It's very slippery and generally not great, Is this your first platformer like game? It looks lime you used round collider for the wizard, but rectangular collider for the platforms. Such combination doesn't work well or not at all.
Your ground check gives me extra jumps even when im touching a platform from the side.
You can also hang on a sode by hlding a direction key towards the wall.
If you fix all the movement issues, and add some feedback to action in the game (like how many ghosts/souls i need to level up) it could be quuite a nice game. The "I'M frustrated" room in Will you snail is quote fun even when it's just collecting one, same thing .
