Punkt core gameplay revolves around a 2D map. The aim of the player is to collect coins one by one which randomly pop up in the arena. As soon as the player collects the first coin, an enemy will randomly spawn from a side and oscillate uniformly through the length of the screem. As the player collects one coin it triggers another coin at a random location and one more new enemy appears and restricts our motion. This goes on and on until contact with an enemy which results in immediate death.
The goal of the game is to survive as long as possible by dodging the enemies and collecting most number of coins possible. The number of coins that the player picks up before dying constitutes as the score.
