Wait a minute. A beginning cutscene ? A story ? CHARACTER SELECTION ? And MULTIPLE LEVELS WITH THAT ? ... I'll have to call Dumbledore to tell him I know were his time-turner is xD !
All jokes aside, I really enjoyed your game. At first glance, I didn't thought I would like it so much, but each new ability brought so much depth to the gameplay, it made the whole game a really good experience. The gameplay is a huge success.
The art is nice for a 48h jam ! I was a bit surprised by the "whiteness" of the first level, but then I understood that, with the happiness growing, each level had more and more colors, and that's a really neat idea !
The only little drawback is that it's fairly easy to stuck the enemies behind a wall so heal them, but I won't ask for an elaborate AI with pathfinding for a 48h jam (I mean, there is already SO MUCH !)
Congratulations for your entry, I had a great time playing it !
