Greetings!
The aliens need nutrition for their body and they have found the way how to find it on the Earth. Using the power of mind they can find necessary nutritional elements. This task is still challenging and the mind power can be exhausted quickly. The aliens can meditate to recover the mind power and continue using it for different abilities. There is still a lot of work on testing and balancing these features, but it is already playable. Also, the aliens interact with water in an unusual way. They don't have such liquid on their planet, so the interaction activates rough chemical reactions and releases some forces.
Here is video demonstration with using of the features:
Thanks. The flickering is a feature that highlights active spots for nutrition. Animations and UI are still in development, I try to do my best to make them smooth and good looking.
