Hey thank you so much for playing and for your review!
It's definitely not on purpose that obstacles are unavoidable. Unfortunately I failed to tweak all of them in time in such a way that there is always a possibility to avoid them. There is one obstacle which was designed to look impossible to pass, but actually has a small opening that player can use 100% of the time, but the rest of the obstacles just weren't optimized.
Being able to move on the x axis at least to some degree could definitely be intersting! Thank you for your suggestion 🙂
