Very basic click around to avoid the cone of sights of guards, with occasional puzzles, think The Marvellous Miss Take but in a dystopian base. I dropped after episode 2, neither gameplay nor story was grabbing me.
The Marvellous Miss Take at least made it more interesting as you progressed through halls in the house, though, with the additional obstacles. Do they even bother with that in Republique? I think my only issue ever with The Marvellous Miss Take was the POV, actually.
