Hangtris 5.1.1
ld style DOS Tetris game which appears to work in XP without installing special software like dosbox. More than 40 different shapes of blocks. Use a mirror and turbo move function to fit the blocks in an original and fast way. Use bombs to explode them while falling. Sound goes through internal speaker on dos machines. It may be a challenge to get sound working in Windows but we succeeded in Window XP by entering device manager and enabling the hidden beep device. Restarting computer was needed. Probably the only program in the world working on both DOS and Windows versions. Small size game and no writing in system files; easy install/uninstall.
