Wow this is sick. The sounds are nice and satisfying, the controls are smooth, although a little difficult at the start, but I eventually got the hang of it. I wish this had upgrades so I could get stronger but it's still really fun as it is.
I like the movement it's quite smooth, the sounds such as music and the collection sound are very loud, also I managed to get stuck in a tree, you might want to make the window size a bit smaller, as it's a little to tall, and I can't see the top and bottom.
This is cool, I struggled with jumping a little, but once I got the double jump, it was much easier. I like the music made me feel like I needed to rush.
