I was waiting for a clever time manipulation game, and you delivered! I liked the different tools, and the way it was pretty clear what to use for each puzzle. Too bad I couldn't complete the mission (since the demo ended). Nice piece of custom art for the character as well. I had to chuckle when I won 1 million dollars and the guy in the store just casually handed it to me. No biggie. Just an instant millionaire.
I didn't find the game too buggy, but definitely worth some polish. Using time skills at the wrong time often doesn't make sense. Like freezing or slowing time doesn't change how people interact, or freezing time just tints the screen while nothing else ends up changing.
It could be tough, but just about every interaction should change depending on what time magic you've used. NPCs should go silent when frozen for example.
Having some sort of HUD with the time magic linked to Common Event Buttons would be really nice too. It is inconvenient to check out the menu over and over.
Overall, loved the creative idea and execution which (mostly) worked.
