Thank you AlveKatt for this long review. As I'm currently putting together the next release of the game, every feedback is important.
For starters, there is already a fog effect to perceive the distance. It's not as blatant as your Scratch game, but it's there. I'll try to augment it a bit.
Sorry, no easy mode. I make tough games :D
But you can play with a gamepad, it's much easier.
I tried to compile a Linux version, but for that, I need to compile the external libraries for Linux too, and it's not that simple... What you can do is install Wine on your system. Omeganaut for Windows works flawlessly with it.
I'll see if I can access Android vibration from ZGameEditor for a better haptic feedback. Do you have an example of Android game having a good haptic virtual joystick?
