i was playing and it said i got a new character, and its called magicat, but i cant equip it.

for unlocking some skins (specifically the ones that change the character's names) I need to restart the game client to equip them. Also what does the in game money do?

So, can i get the game for free on Steam?

I have the discord version, will I be able to play with those that have the steam version?

1. Are there any promotional content? (I.E. Anything only available for a limited time or more complicated than just buying DLC) 2. Is there anything permanently missable, even rewards for fulfilling specific conditions? 3. Is this game identical on all platforms, including the Switch version having an in-game achievement system? 4. Are there any bonuses for having save data from a different video game?...
