You guys have put lightning in a bottle with this game. You made a completely playable and deep metroidbrania (not the greatest term but fitting) in a weekend?! Such games (reminds me of Leap Year) are rare indeed and give that illusive feeling of discovery as if you're slowing learning the language of games again. Just for a moment everything is new and anything is possible. Discovering how to make fire anywhere and practicing that maneuvre was total *chef's kiss*. The secrets were doled out at a perfect pace that encouraged exploration.
Not only that but you made it with its own narrative and unique character designs and some gorgeously drawn art! Absolute wizardry.
The final rush up the mountain with a rapidly shrinking timer was (pardon the pun), peak. As a Sisyphus fan myself, narratively the ending was perfect as well. We must imagine Sisyphus happy. The best take on a classic story.
Perfect 5/5. Polish up the environment and game juice and release this on steam for the world to experience please.
