I am at the last level, where I've been stuck for years.
The horrible buttons/controls on my phone made some of the trickier platforming more frustrating than the game actually is.
I think the game was OK...but the level design/platforming was seriously compromised by the screen size/ratio and horrible hardware buttons on mobile phone.
I actually thought the aesthetic was interesting (classic bonk sprites juxtaposed with photo-realistic backgrounds/platforms). Granted, this Plan doesn't sound good on paper but the contrasting elements work nicely.
