Twinbee

Getting started: After starting the game through the emulator, you will see a title screen in Japanese. Press Enter to start. The game immediately drops you into a vertical scrolling stage where your ship moves with the arrow keys and shoots with the S button. The core loop is simple: fly upward, shoot enemies, and collect the floating bells that appear when you destroy certain foes.

Those bells are the key to powering up your weapons. Grabbing a bell changes its color and the color determines the upgrade you receive - for example, a yellow bell might give you twin shots while a red bell can add spread shot. Avoid enemy bullets and keep an eye on your ship's speed (controllable with the up arrow). If you die, you restart at a checkpoint. The MSX version is a faithful adaptation of the arcade original so the goal is to survive all stages and achieve the highest score.

Since menus are entirely in Japanese, there is not much to configure outside the game. The gameplay is intuitive enough to start blasting right away. Focus on dodging and learning bell patterns to get stronger. The game is short but challenging.
