Hello, Tereza here :D! We are thrilled you enjoyed our game and really appreciate the feedback on what you enjoyed the most. The fun thing is, we (not me, haha) ALWAYS forget about the Z-rotation, so whenever we press "play" for the first time after having some basic movement implemented, this is EXACTLY what happens - as if we haven't made a platformer before.
Thank you again for the kind words, they made our day. :))
