Yeah, the per-character restart used to be in the game's first version, and it might make sense to enable it on the longer levels, to at least have some sort of checkpoint. I'll mention that so we can maybe add that feature. Thank you for the review!
EDIT - I just realised that you meant the character switching with tab - yeah that is a bit unfriendly that you need to do it before moving indeed. If enabled during level, it might be nice to have a tab hold interaction or a pop-up with a switching character that you have to repress to confirm to counteract accidental tab pressing during level that would teleport you back. I see what you mean now
