I think the game has some kind of fatal error in it that triggers at some point. Every time I got to the last level before the congratulations level I experienced weird behaviours, like enemies not colliding with me, me not being able to pick up the hearts. One time the game proper crashed as well. Not sure what's causing it, but it may be connected to the Xray vision feature. This feature, always had problems for me, and in the last levels I couldn't use it at all.

The character controller has a very narrow window for modular jump, and the window has a huge effect. The jump can be doubled in height with very little input time. There is no grace jump.

The art is consistent and palette use is generally clever. It's easy to tell FG from BG, with the exception of the grey colour. There is a slightly darker grey used indicating that's BG. I think it needs more contrast. Also, there is no proper background. It's all black, which suits the game alright enough, I suppose, but I would like to see more detail there.

The music arrangement uses very high frequency tones, which are irritating to the ear. I'm grateful you added the mute function. I did listen to it all, and it's also very short, so it's irritating and repetitive. SFX are serviceable.

I don't see how the game conforms to the theme. I think the rationale is that the Xray vision aspect is "the lie", but in that case, Hitman, Lara Croft, and Batman are all liars too.

This game had potential to be a fun little platformer, but it's negatively affected by A class bugs.
