Bat

The bat is the only flying enemy in the game, and flying makes them extremely difficult to deal with. Bats will often attack you in twos or threes so it’s important to take out the ones in the most dangerous positions first. Since they come in waves, they will almost always arrive staggered and don’t necessarily all have to be killed. Obviously, killing all of the bats will give you a better score but you have to weigh the risk of engaging or avoiding. When encountered with the tall walkway obstacle, there will usually be a wave of bats protecting the item that awaits you; these bats will attack you when you get near the middle. Prepare for this and either avoid the bats by jumping over them or killing them fast and taking your prize.
