You are welcome! :)
Also i forgot to mention last time that sticking to the wallls sometims feels too sticky and as i understood the only way to get down is to jump and don't touch original wall and potential close one, all of this can be really tricky sometimes while i think some button would be great for it - for example down button or mb double tap on direction opposing the wall or something like that. I was playing Super Meat Boy a while ago, i even found free original version (on flash - https://www.newgrounds.com/portal/view/463241), can be a good reference to do it, it felt more lively and intuitively right there even tho i prob remembering full game - https://store.steampowered.com/app/40800/Super_Meat_Boy/, but i've tried at flash version now and it's fine there, enough stickiness, can drop anytime. I understand that you have slightly different mechani - you are not sliding down at your game, so that's a big difference, but prob worth to consider
That balance between challenge and fairness is tricky to get right, and your thoughts are super helpful for me as I refine the level design.
Ye, i agree, difficult to find the right balance. I would say that in levels before 4th it felt fine what make sense - you had more time for polishing them, so i'm pretty sure you can do it, keep it up! Glad to help :)
