You may say you need an artist, but that’s some good scenery, combined with the ambient sounds.
At first I was very confused because I was using A and D but unlike the arrow keys, W and S don’t work.
The squirrel needs a bit of coyote time or to be able to jump while holding the jump button down instead of when pressing it. If I try to play it faster, I keep sliding off logs.
Regarding people saying there’s no increase in difficulty, I agree, but I got an idea - making it so that you can carry an unlimited number of acorns but each acorn decreases your acceleration and deceleration so the squirrel becomes harder and harder to control and the player has to make a compromise between ease of movement and carrying capacity.
