Night Mode is present;
Tower achievement is a bit of BS, I doubt many people could get it on accident as part of "I've been clicking on things and noticed this highlights (like dog one), so I kept going for more of those and got it eventually", especially sine on that part of the picture it doesn't have cracks drawn on it (instead it has cracks on walls that do not react anyhow to you clicking on them).
Overall it's okay-ish, would give it neutral recommendation if there would be such an option.
How much it worth price-wise you have to decide for yourself, taking into account that it offers 10 minutes of gameplay.
