heal. is a simple game; stay alive! collect circles and deflect squares to keep going - the game's health is always decreasing bit by bit but you can help! circles will improve the health when they are absorbed into the center so make sure to let them reach it. however, squares will decrease the health when they reach the center so it's best to deflect them using the rotating defence piece. you're not alone, help is here - there are three special boosts to use throughout the game which can all be unlocked by either absorbing or deflecting shapes (see the 'boosts' page in the game for more information). these will help you out in unique ways so use them wisely. (all you need to know is in the game, i hope you enjoy playing heal.)
