CuDo is a 2D arcade game about collecting as many points as you can while dodging enemies coming at you from all sides. There are several powerups to collect to make your life easier (or harder). The more points you get the faster the enemies are coming at you!
In the game you play as a little blue square trying to collect as many of the yellow checkpoints as you can. You have to be careful though as there are red enemies coming from all sides of the screen just waiting to run into you so you better dodge them! The enemies get faster the higher your score is, so while the game starts out fairly easy it will not remain that way! To help you with your goal there are powerups you can collect that spawn every now and then.
There are different types of powerups that the game can spawn. After you collect them you will get an effect that lasts for a couple of seconds. Here is a short overview of the powerups and their effects:
