You can press the END key to respawn to the closest activated obelisk at any time. However, it will consume all of your energy.
The final release version will provide a minimum of 8 to 10 hours of gameplay with various options to diversify the challenges, such as difficulty levels and optional achievements.
Spheriums has been in development for more than 18 months. Being two developers working on the game, we know that the best ideas come from the communities. We had a few internal beta testers, but we believe it is time to open Spheriums to more users through Early Access.
Our approach is to work with the community to help us improve all aspects of the game. We want to enhance the gameplay, the design, to name a few, by fixing issues and exploring new ideas to allow everyone to experience the great game you deserve.
