Thank you so much for your feedback !
I saw you playing on YouTube, and I would advise you to progress further in the levels because there are more puzzle elements that you discover gradually...
There are two game modes: the exploration part to finish the levels, and the speedrun part which depends on memory, where you have to beat the levels as quickly as possible ( almost all levels can be completed in under 10 seconds ).
PS : Regarding the controls stopping after pausing, I haven't been able to reproduce the bug to understand what happened because everything is working fine for me. For the level with the dash, you can only go up on the right side ( you need to switch while jumping ), it will be easier.
