This prologue was quite outstanding on its own - while the gameplay itself was very simple (no choices or complicated mechanics yet) the game really made the experience worthwhile thanks to its art and music. Artwise, it combines two completely different styles, both of which are exceptionally well done (I particularly enjoyed looking at the backgrounds), although it's a bit hard to tell whether they clash or not - the difference in resolutions (between the sprites and the background) can be offputting. Now when it comes to music it's hard to tell anything else but good words - it was very climatic and pleasant to listen to, I was genuinely surprised by it. These two elements work quite well for the story, which may feel like it has been done before (framed for murder, going back in time to solve a mystery etc.) but it leaves many open possibilities to surprise and entertain the player. Overall, it's a very promising start to the full game.
