I’ve tested the game on PC and mobile. I could not get a controller working on PC, so you’ll have to rely on keyboard inputs. However, there are touch controls if you play in a mobile browser, which means you can play on your phone any time you want, since the game is free.
It’s probably going to be a bit - there are 7 chapters planned with 1-4 out now and 5 coming out next year. I don’t think anything has been announced for chapters 6 and 7, but I’d think end of 2027-mid 2028 would make sense for it to be complete.
That being said, I haven’t jumped into Deltarune yet for similar reasons, but I’ve heard each episode tends to have a ‘Conclusion’ instead of cliffhangers and players have felt satisfied waiting for the next part. I’ll probably pick it up in the next year to see how it is.
I see, thanks!
