Really great concept, I really encourage you to complete this project , it can really turn into something big.
-The Music and SFX are very suitable and decent
-The particle systems are eye-pleasing
-There aren't that much 2.5D games out there, so it is a very nice experience.
-The game is chilly and relaxing
-I read the details over the theme and the game idea so I will avoid this point.
Overall, The game is very well design .Truly Great job and keep it up!!!
Looking forward for future updates.
