Horace has lovely visuals, a good blend of classical and digital soundtrack, and a fairly good concept for a story. But it lacks that indescribable essence that's behind all good games, the "game feel".

Horace doesn't value your time. At least 50% of the game is unskippable cutscenes. Not a single cutscene is skippable. Horace's voice, which is a synthetic, unchanging voice used for every voice in the game, is cute and humorous only for the briefest of moments, before you realize that you are going to be hearing the exact same tones in different combinations for the next significant portion of your life. He commentates over every cutscene, speaking in quote format for other characters, and speaks quite a lot outside of cutscenes as well. I never want to hear this golden sod speak again.

The story seems to take some interesting twists in the time that I played, (up to chapter 8 out of 22) but it's such a slog to get through each chapter. Gameplay seems to be slotted in whenever the developer wanted, with dream sequences that don't advance the story taking up whole chapters appearing from nowhere and scarcely being mentioned again.
Overall, Horace's individual components are great, better than passing. But some very big issues crop up in the design of the game that really just make it not fun to play.
