Horizontal shooter. Three ships to choose from that each go through three different shot types as you max out your weapon upgrades. The difficulty of the game comes more from how long it takes to max out your upgrades, potential upgrades that can temporarily make the game more difficult, and a checkpoint system that has you lose your upgrades. The main way to stay alive is through frequent shield drops. You can also swap between two sub weapons, higher damaging missiles or faster shooting lasers. Firing the main and sub weapon together lowers the power of both, which probably wasn't need. A lot of sections where a wave or waves of enemies suddenly appear from multiple angles and have difficult to avoid attacks unless you knew about it ahead of time due to your fairly slow movement speed. Has more subdued soundtrack but I liked it. Multiple routes to choose from but some levels are fairly similar to others and many of the bosses pose little threat.
