Thank you for the feedback.

I'm glad you had fun with the game.

It was a real challenge to have a level that is readable and playable. This is why objects are in color more vivid in relation to the environment. Like that, there is always a colored pixel that is visible. But it's not ideal when the camera shows the whole level. One of the solutions would have been to have more closed areas. The fog would have another very nice solution but which I did not think then.

Thanks again for the analysis;)

Thank you very much !

The gamepad was also a trap if we compare with the mouse keyboard. Some orders are not present. For example, you can not run. It was intentional, to give another way to approach the game.
This is also why there are four ways to die. :)
