We are glad you enjoy it that much! Thank you so much for playing our game demo, and giving us this lovely feedback as well!
As we are short on people, we might keep this sketchy style for the CGs/cutscene images, but in exchange, we will make a lot of them so that the player can have a much better understanding at the story. If we finish them earlier than the schedule, we might color all of them as well! ;)
And "ICE" is not relevant to the later plot. It is a reference from the game "Zero Escape: Nine Hours, Nine Persons, Nine Doors", where the word "ICE" is one of the main clue to the whole story, as well as from our previous game "blindXpot", in which the player has to press "1CE" (basic calculator buttons) to process to the true ending.
(There is no harm in sharing this one, as the true ending requires other factors to get to the true ending.)
You have motivated us a lot, and we will try our best! Thank you so much again for your kind words, Weakest Imp!
