One Button Games 5-in-1 vol. 9

One-Button Games 5-in-1 | Vol. 9 is a compilation of five fast-paced arcade games with the quirk that they can be controlled with just one button, exploring different genres and game idea and extending what's possible with the length of just one button! (UNCTRL) There's an alien invasion and you are the last space barrier... and a malfunctioning one at that! You can only shoot one guided missile at the time, with the only problem that the guidance system is broken! Launch the missile and quickly tap the button to propel it up and down to try and target the enemy ships. Sweep as many enemy lasers as you can with your missile to multiply your score when you hit an alien invader. The game is over when an enemy ship crosses your line or when you get hit by a laser. (B MATH) It's time to B MATH... and BE QUICK about it! You are presented with a simple equation (sum, subtraction, multiplication and division) and 5 possible answers, with the system quickly swapping through them. You have to select the correct one before the timer runs out. Gain points depending on your results. Correct answers will restore a big chunk of your remaining time, and incorrect answers will subtract it. The game is over when the time runs out. (BOTTOP) From bottom to the top, run and jump along! You and your doppelganger find yourself in an endless running corridor where you have to avoid a barrage of enemies. Gain points jumping over them but always be careful as your doppelganger will mirror every move you make. You can also gain extra points by jumping so high that you connect with your mirror image. The game is over when either side touches an enemy. (TEETER) There's a tether that is keeping me... teetering! Control a machine where you can move different platforms to guide different balls falling through. In the bottom, there will be slots containing score, but also slots that will give you more platforms... and slots that will remove them! The balls will also have different materials that will bounce more or less, so be careful. The game is over if you run out of platforms (REFLECTOR) Looks like the alien invasion was not controlled in UNCTRL, so now, it's time to retake the ground! Control a ship with a special reflector shield while you try to clear out dozens of martian tanks invading Earth. These tanks will relentlessly shoot you but your shield will deflect the shots. You can overcharge your shield to reflect a shot and send it back with extra strength to take out as many tanks as you can with a single reflection. If an enemy shot slips through your shield and hits you, the game is over.
