PacBoy and Mouse (199x) (Watara)

A very fun and interesting game. The main character is a boy who took to free the city from the invasion of nasty mice, which, in addition, scared his favorite girl.
The gameplay boils down to the following. On the map there are many blocks that form a maze and a few mice running purposefully behind our hero. The goal is to destroy all the rodents by pushing blocks on them.
A block can be pushed only if there is an empty space behind it, otherwise it simply burns. The mice themselves can also destroy blocks (which they do). However, there are some iron blocks on the map that can only be pushed.
