Thank you for the feedback, it's really appreciated. In the immortal words of Lt. Commander Data "Blown out, not sucked out in to space. A common misconception" ;) You're absolutely right. I'm very glad you enjoyed. bringing back nostalgia for Shadowgate was the whole purpose of making this game and it's always good to hear that it reminds players of that. As for the water supply chemical puzzle; there actually is a way to find the combination through examination of previously discovered elements on the ship. The reason for the "guessing game" was to be more lenient. As for the space suit glitch; thank you for the detailed description as that helps with our improvements.
I did identify the chemical combination in the manner you had intended. I just mean before that happened, I found the water mixing system unintuitive. From what I recall, after randomly adding a few chemicals and then examining the system it would say something like "the chemicals are mixed and now you just have to run it," and then pressing the button would just cause a beeping sound. But regardless I loved the game, so thanks again!
