Hi! Thanks for the review. From what I saw in your video, you had trouble with the small puzzle in the forest... It looks like I need to add a better explanation on how to complete that level, since people who aren’t used to playing video games are finding it difficult. That said, the level is indeed possible to complete.
Spoiler: You just shouldn't break all the boxes — if you leave two, you can jump on top of them, climb the mountains, and shoot the targets to continue with the jumps. :)
Regarding your comment about the controls being difficult — that mostly comes down to comfort. For people who are used to playing with a keyboard, using "WASD, Shift, Q, E, and C" isn’t really an issue. However, just a reminder: you can also play using the arrow keys (Up, Left, Down, Right) along with Z, X, and C if that feels more comfortable — or even use a compatible game controller!
