Your entry is very similar to mine and since I am so used to use WSAD to move and your game doesn't have it - I understand your comment on my game better^^
Anyway I would prefer if jump was on space or anyother key but up - I found wall jumping very hard with switching sides and tapping up in the right order all with one hand cramped on the arrow keys while the other hand waits on q
Also since your other dimension is completly hidden and you have to swap mid jump it makes actually hitting your target very difficult and you have a timer on the second dimension - so I never got past the first dimension swapping level....
