Hi! Thank you for your comment - I will check out your game.
To address your concerns:
The swap in controls is due to the characters having different keys in order to swap. The long haired character (Lucille) uses E, and the one with shorter hair (Robin) uses Q. This is to prevent a game breaking issue where if someone gets both onto a switch it would disable both characters with no way to reenable them. I will add to the wording to make it more clear which character is being disabled.
As for the sounds - I was going to add them on Sunday but had an issue in Unity so had to forgo that in favor of finishing everything else. I do plan to go back in and add SFX and music :3
I am very aware of the tediousness… I am going to revisit all the levels that take a lot of time once one knows the way to complete it, and make it more of a puzzle versus slow tread to the finish.
Thank you again for your comment!
