Wow, what a creative game idea for a game. It reminds me a lot of jet pack joyride, this could have easily been one of the vehicles from there. I love the art, sounds, music and vibe.
It's a very punishing game though, even the first level took like 30 attempts to get through. I have some suggestions and notes.
The first instruction on the sign looks like a 5 not an S so I ended up referring to the instructions to see how to play. After reading the instructions and getting past the first obstacle, I then saw the W sign which made me wonder why there was no S sign. And then I saw the S sign and understood why I missed it.
The red boxes in the background are a little distracting. As most things in this game kill you, it took me a very long time to realise that they in fact do not, and I was making the game 10x harder for myself by trying to avoid them when I didn't need to.
The controls are also a little confusing, you press down to go up and vice versa.
Overall, a well polished game and I enjoyed playing!
