I'm not too good at playing videogames, I'm in the second level. I think I haven't found any secrets...
Out of appreciation for the grueling challenge of platformers before it, I designed this game to be very challenging, so it's understandable to have some trouble with it.
The heavy controls are meant to encourage strategy over dexterity, and the secrets are a natural evolution of that sort of gameplay mindset.
I plan to make a behind-the-scenes video in the future that shows off how I designed it so if it's too much a challenge now, the full game will be shown in that video!
