The unfortunate thing with 'Celine' is that there's just no music/effects and that's something I really look forward to when playing a game - it's really important for immersion. Even just something simple from the RTP would've been better than nothing!
It feels quite unfinished and that it would need more time to get it up to speed and to a standard you'd like. Also please teach the player at the beginning with a tutorial about the controls/what the objectives are! That would be super helpful :) I hope you continue working on the idea to strengthen it.
