Just watch the creatures and plants. You can hold LMB or tap to see the health and energy of each creature.
Fixed Bugs: 1. The glitch (1st bug) was caused by all the plants having the same ID. I fixed it and now the creatures can find targets again. 2. BAND-AID FIX — Removed the plants' ability to reproduce in favor of a simpler system that constantly grows more plants. The creatures have also lost their predatory instincts, due to the fact that they will tend to reach a point where they kill each other for no gain (they don't eat meat), however, they can still damage each other if they hit each other. Bugs: 1. The Al of the creatures seems to glitch after they reach their target, causing them to get stuck in place and slowly die due to energy loss. 2. Very similar to the 1st bug. When the plants reproduce and are then eaten, they fail to delete their position data from the list. (Somehow fixed itself!)
