WARNING! Spoilers for season 2. Don't say I didn't warn you...………
ok here's the spoilers: ------------------------------------
Season 2 spoiler: Our beloved heroes, Adam, Mira and Kai along with the people from the opposing team last season, actually turned out to be digital copies of the real Adam, Mira, Kai, etc. As a result, they stay in the digital copy of their world thinking their safe and happy. Unfortunately at the last second, the snail that killed Skeet (the digital copy one, not the real life one) comes back at the last second to terrorise the digital world of the digital copies of our beloved heroes. Apparently, Adam and Mira replaced Reeve with Kai and that Vanessa cheated before the start of the game in the first season which caused the glitch and corruption of the game in the first season. Season 3 might come due to the arrival of the big snail who was the pet of some French professor who tried use them for experiments in his mansion.
My opinion: I think the ending kind of sucked, didn't really hype me up, whereas the ending of the first season totally blew my mind. Though, season 2 is pretty incredible in terms of story but animation. Not so much.
