I always found it odd that in the 2nd part of this game, there were no outlets to replenish your energy, making it rather difficult. Yesterday, I accidentally discovered that the sparkling robot is in fact here to help us refill our energy (I was trying to kill it ;D).
I'm not sure that was a known thing, thus I'm sharing it with you. Anyway, it took me almost 40 years to discover this!
Of nice found !! :D
Merci Jean-Marie !! :)
