I know that this game crashes when exiting sometimes. It seems that this bug exists from v1.18 (01/14/2018). On v1.18, I switched the build method from 'mono' to 'il2cpp'. The reason why I switched is that 'il2cpp' is more compatible than 'mono'. However, it seems that 'il2cpp' is unstable for this game. So from this version (v1.25), I decided to switch back to 'mono' and publish 'il2cpp' version as a beta (You can select in BETAS tab). If the game doesn't start at all, try 'il2cpp' beta.
