hi! you have 2 different limitations: 16 inputs (walking forward, backward, left, right, cast a spell) and 16 seconds to finish a level. the rules on how to deal with enemies are in the description! (use spells of a certain color)
your goal is to kill skeletons (they have colorized particles) and turrets (above the altar on the third level) and not exсeed the limits. when you do it, the screen will be distorted and you will be teleported to the next level. there are only 3 levels. on the next level there will be a ghost copy of your previous inputs, dont touch it! otherwise (and if you dont fulfill the goal) you will be sent back to previous level.
sorry, the description was incomplete((
