Very stylistic and faithful to retro handhelds in terms of graphics and audio.
Simple and pretty well executed. I like how the crosshair changes as it moves over terrain of the same color but sometimes I still had a hard time seeing it. That said I think you did your best given the limitations of the palette you were using.
Like the others I couldn't make it past the fourth night. I think that's where the difficulty starts to ramp up.
I think players who like this type of game could easily get addicted to this and play it for hours.
