"English Typing Practice - Acid Rain" is a typing practice game available on the Android platform. The game, developed by 돼지왕왕돼지, falls under the category of word games.

In this game, players must prevent drops of acid rain from reaching the tower by typing the corresponding word before it reaches the bottom. If the acid rain hits the tower or the sea at the bottom, the tower will rust. The rust level is indicated by the heart gauge located at the top left corner of the screen.

As the levels progress, the speed at which the acid rain drops increases, requiring players to type faster. The game also introduces various "Virus" words, some of which are beneficial while others are harmful. For example, the Clear Virus removes all acid rain words and increases the score, while the Cluster Virus brings additional acid rain drops.

The design and sound of "English Typing Practice - Acid Rain" are reminiscent of the popular typing game "Hanmetaja" from the era of 286, 386, and 486 PCs. Players have the option to select the starting level and can compete for high scores by adding their names to the ranking list.

This game provides an enjoyable way to practice typing skills and can be a fun activity to engage in with friends or colleagues.
