Thank you so so much for your very detailed comment! We did implement your 1st, 3rd, 4th, 5th and 7th recommendations!
We unfortunately did not implement cat boss and the scenery changes because they are major changes and are hard to do (although they are very fun ideas!).
We also did not implement dash being replenished when you land because we designed the level around the current mechanic.
All other features and fixes are added and also I fixed the jumper platform sound bug ^^
