The jumping mechanic took some getting used to, some Coyote Time would have been nice. The aesthetics look really smooth (the buttons on the main menu are a cool idea!). Everything looks maybe a bit simple but very well polished.
Even with seemingly endless lives, it gets really hard really quick!
I couldn't get past the moving spikes in the third(?) second level...
Is there anything more to the lights except as light sources? The shadowing looks great anyway.
Nice touch: When a tombstone covered a light that area got dark as the light source was blocked out.
