About Hydrodynamics of Hope & Optimism
Self-Delusion – A Modern Plague
Are you happy in life? Do you sometimes feel dehydrated? Is the glass half-full or half-empty?Are you prone to self-delusion? Hmm… I see.You are declared the target audience for Hydrodynamics of Hope & Optimism- in short, H2O!On the topic of water
Do not fret, self-delusion is not an incurable condition!One of the best solutions to prevent self-delusion is drinking water! It is extremely important to stay hydrated during your day, as a lack of water could lead to several conditions, such as headaches, stomach-aches, headaches, syphilis, headaches, cancer, headaches, job-loss, and many other problems including headaches.To further illustrate the importance of water, please note that you are composed of approximately 60% of water (70% if you’re a child). Some parts of your body have an even higher percentage of water: your brain, for example, is composed of almost 90% of water (source: me). If it helps, you can therefore see your brain as a jellyfish. With eyes. Yes, I know it doesn’t help.But now, how do you know if you’re self-delusional?Hydrodynamics of Hope & Optimism
Discover the shameful fallacies of your brain by using Hydrodynamics of Hope & Optimism -in short, H2O! With this software, you can be declared sane. Officially sane.How does it work? You will be asked to fill a series of glass halfway. Of course, you will probably fill them a little too much, or a little not enough. Our counselor, TeaTotal, will analyse your glass-filling trends, and then assess your mental state to see if you are sane or self-delusional. No refunds.Do not fear, happiness is within your grasp!Stay hydrated!What this game features
Wait. Is this actually a game?Yes. No. Who cares?If you actually care, the only element of answer the team shall provide is the definition given by Salem, K. and Zimmerman, E. in their 2003 book Rules of Play: Game Design Fundamentals: "a game is a system in which players engage in an artificial conflict, defined by rules, that results in a quantifiable outcome."Now then, the artificial conflict here is the 25 or so glasses to fill and 20 questions to answer leading you to a quantifiable outcome of questioning your life choices, although existential doubt should emerge around the 15th glass. And at the end, you get a nice final Hope & Optimism score because god knows ya’ll gamers need a satisfying conclusion.Of course, for the sake of achievement-addicted Steam players, this game features 17 achievements for increased replayability value (wink wink, nudge nudge).Won't somebody please think of the gameplay?
Oh, right. Well, you will use a whopping FOUR buttons to play this game!Hold space to fill the glasses, only to release it when you think you've reached the halfway point.Press left or right when choosing an answer to declare which glass you shall fill.Press enter to advance in the therapy (i.e. the dialogues).Technically, you can also use escape to quit the game, but we don't think it counts.Hydrodynamics of Hope & Optimism — game info

Mmh..you did great ! Although I did feel a bit force at the choice "I'm not sure.." and "I lied". I was sure !!1 found this helpful
It was really fun! Thought provoking questions with a simple gameplay that compliments the ambience of the game nicely. Definitely recommend!1 found this helpful
Pretentious. No real choices, not even real percentages. Grind for achievements. I hoped for a hydro homie game, but it's not that.1 found this helpful
Hydrodynamics of Hope & Optimism is one of those games where I was not completely sure what I was getting into at first. The whole thing is built around filling glasses to what I think is halfway, while a counselor named TeaTotal asks me questions and judges my answers. It sounds ridiculous on paper, and honestly it is, but I think that is part of what makes it work. It takes something as simple as deciding where halfway is and turns it into a weird little examination of how I see things. The actual gameplay could not be much simpler. I hold space to fill a glass and release it when I think I have reached the halfway point, then I use left or right to choose between answers and enter to continue the conversation. There are around 25 glasses and 20 questions, so there is not a huge amount of content here. What I liked is that the glass filling is simple but surprisingly easy to get wrong. I started second guessing myself more than I expected, especially once I realised the game was paying attention to my habits. TeaTotal is definitely the star of the whole experience for me. The conversations are funny, strange and sometimes much more uncomfortable than I expected. The game uses i…
Quite a funny short game! The controls are easy to use, and the game is quite accessible (even for French people): you just have to fill some glasses with water and let this doctor-ish help you assess your hope and optimism. That's it, that's the game. Expect some real personal questions (like your favourite animal), some tricky glasses to fill and a lot of judgemental looks, but that's for your own good. The game lasts less than 30 minutes if you're not a perfectionist. Otherwise, you're going to be a real good glass-filler (and probably a bit nut too). Obviously, don't take that game too seriously or personally, like the other reviews :)
