Well, theoretically, no! :) I (Vittorio) am making the greatest part of the workload. I do all the art, scenario, game direction and design, and I manage all the work from all the other people involved in the project. And I'm making this 100% for free, and I tell you, it is a LOT of work ^^'
I have the help of a programmer (Matteo), who is a good old friend and is taking part in the project with passion and not much money.
So, if you cut our parts from the budget, everything is pretty much feasible.
I already paid for music, demo text translations, and few other things I needed for the demo to be complete. I just need the extra Kickstarter funding in order to pay some other things necessary for the full game, like few extra music tracks, a professional English/Japanese full translation, a PR for marketing etc.
If the campaign is successful, I'd like to share a new second part of the demo just in time for Summer 2018, for Kickstarter supporters. Oppaidius Summer Trouble! is a game you should enjoy during the Summer, after all!
