Also no branches means no need to replay
Most (sadly not all) VNs do a good job minimizing repetition when replaying for alternative routes/endings. Fast-skipping text already read, highlighting choices you already took, or even having a flowchard so you can skip to branching points.
my recommendation will be Silver Case 2425.
Silver Case 2425 looks really interesting! It's a pair of old VNs from Suda 51.
But I think I'll go for Atri first, mainly because it's the shortest of the three.
I think this episode shows that the production team is lacking in budget, but also shows that they care about the source material and are trying to do their best within their limits - and decent direction and voice acting can go a long way towards it.
That Atou face was just perfect.
