A cooperative game about building railroads. :) Goal The cats and dogs have made peace! To celebrate, you and your friend need to build a railroad together that connects the two countries. However, cats and dogs don't speak the same language, so you need to communicate without words to align the tracks within three days and devise your strategy. :) How to Play - Communication through words is not allowed, only gestures. You can only see your own screens; - You will have 3 days to build a railroad that goes from your starting points to line 6 of the grid. When aligning the cell phones at the end of the game, the railroad needs to pass through adjacent tiles for the game to be won; - Before reaching line 6, you need to pass through the two stations distributed on the map, which will give extra resources when reached; - Each day has 2 phases: in the morning, you can share resources to help each other in the game. In the afternoon, you can position the rails on the grid. - By combining wood and stone, you build a rail; - Obstacles on the map can be bypassed or passed over using two rails instead of one. :) Resources Rails: can be placed on the grid Wood: found in the land of cats, on forest tiles. Stone: found in the land of dogs, on mountain tiles. EARMUFFS ARE RECOMMENDED FOR A MORE FUN EXPERIENCE :) THANK YOU FOR TRYING OUR GAME!

Everyone knows the feeling: you try to plug in a USB flash drive, it won't fit, you flip it, it still won't fit, and somehow the first side was right all along. USB SIMULATOR turns that universal struggle into a tiny, funny pixel-art game. HOW IT WORKS Tap or swipe the screen to try to plug the USB stick into the port. Sometimes it slides right in. Most of the time it bumps against the port, flips around, and makes you try the other side. Just like real life. CHOOSE YOUR PAIN • Easy: 30% chance to plug in • Medium: 20% chance to plug in • Hard: 10% chance to plug in • Automatic: Hard odds, but the app keeps trying for you Tap the "i" button on the difficulty screen anytime to check the odds. FEATURES • A 3D USB flash drive with hand-made animations • 4 random pixel-art victory animations when you finally get it in • Hit and miss streak counter • Records: your best streaks for each level • Retro sound effects • Retro pixel-art look with chunky buttons • Four modes, from Easy to Automatic • Pause and exit whenever you want • Available in 32 languages • No ads, no accounts, no internet required The perfect meme game for anyone who has ever failed to plug in a USB three times in a row.
