I did not like Alpha 2
I honestly thought it was a titanic downgrade from Alpha 1 and Pre Alpha. The neighbor was too fast and didn't really use smart tactics instead b-lining it to you. I thought the house was also too small and also a downgrade from Alpha 1. Alpha 1 still mixed the weird uncanny feeling with the odd puzzles with the ability for the neighbor to still intelligently pursue you through every floor. Ditching the multiple floors with the train while keeping the house looking at least mildly believable still for a 1 floor 3 room house with an attic the neighbor can't even enter just felt totally lame and a downgrade.
I also didn't like that they were starting to ditch the more unsettling early Pixar kind of look for the wacky and zany bright silly art style of the final game. The neighbor was also way too sensitive and didn't really lay out traps much like in Alpha 1 and Pre Alpha. All in all, it felt like the start of the generi-fication of Hello Neighbor
