Actually a NES classic port, you have to color all the blocks in the pyramid to advance to the next level. Avoid all aliens - it seems easy but it isn't! Hint: press LB and RB together to open the secret menu where you can save state, and set Display -> Flicker OFF to normalize view if it flickers too much.
An "unsupported mode 13" message upon start is normal (tested working on VisualBoy Advance)
