This is one that looks much cooler than it is to play. I really like the setting and concept for this horizontal shooter... a prehistoric isle in 1930, lol. But your biplane has all this crazy tech from like 2130. The way you can rotate your secondary weapon is very neat, changing its form depending on the angle you're firing it at. You will want all the power-ups you can get to take full advantage of these sub-weapons.

The main problem with this game is that your plane has such a huge hit box, and it's a damn tough game. The challenge is not surprising for an arcade game of its time obviously, but that combined with how easy it is for your plane to go down is a real bummer, because it means you'll hardly ever get a chance to use all those cool sub-weapons. Levels are designed so that you often have to fly into narrow tunnels, which of course are full of enemies and their projectiles. Yeah, this game wanted all of your quarters. Even with save scumming, I can't get through the later levels lol.
