Life sets its own rhythm to everything. For the main character of Langoth his heart beat rhythm plays the most important role - his life depends on it. If he distracts for a bit, a treacherous heart will stop, breaking the rhythm of his life. In Langoth you'll have to carefully control your pulse. Jumping increases your pulse, but you won't be able to avoid dangerous hazards without it. To increase and decrease it you can use bottom buttons. If pulse gets too high or too low, the main character dies. How long will you survive?
