Thanks, Radint!
I was toying with axes trajectory, and decided I like this one. It's actually a spiral with a pretty big arc, but looks like gravity, I agree.
The death screen is supposed to be skipped on any key press (goes back to the main menu), and for me it does work, just checked. Although you have to wait until the "you died" screen fully shows up. Or did you mean skipping the death animation and screen altogether? I'll probably add a restart button to the menu.
