Unfortunately, this trainer appears to be having the opposite effect. Instead of you having infinite health, your opponent does, at least with version 0.13.3251 of the game. Also, Energy cheat does not appear to work, even though at least one hour has passed in game. Perhaps some pointers were moved when it moved to the current regular version alpha instead of the alpha version beta? I will try this one more time to see if there's just something I missed. Thank you for taking the time to read this.
Edit: Tried again, and energy cheat didn't work, again, even after waiting several hours. Didn't test hit points again, so not sure if that is the same problem or not. BTW, I DIDN'T activate all cheats, because if you activate food cheat early in the game, it can prevent you from completing the goal of accumulating 100 food. Do ALL the cheats need to be activated at once, as trainer descriptions says, or should they work normally if activated individually?
