Im not paying 2 times because the creator decided that an update is now a remake and the "original" game was already finished. I think that's not how remakes work, if you decide to continue your "finished" game i think you should've just updated it, this move is very arrogant from the creator. A "That's not my neighbor 2" would've been less obvious than this tbh.
After some research, there are still some things wrong. I guess there will be a reason of why you cannot keep updating the game here, so i'll skip that, but still the problem that you still have the excuse of not asking us for more money for updating it. I think that never happened with other game, when they feel like we got a lot of things, you just put it more expensive for new ppl or maybe like I said you can call it a 2nd part, idk. I guess also not being able to continue the game and starting it all over again disapointed some others ._.
Other thing that you shouldn't do again is doing promises that you are not sure you can really make, like the refunds. And I don't want a refund lol, I payed for it because I wanted to play it and enjoy it. Just keep it!
Well since idk you so much i guess i'll believe you and think you're actually a good person and buy it again when i have the opportunity :P but don't discontinue it again and release it later on any other platform lol
