Oops - I think I somehow I deleted my previous comment on accident. My apologies and feel free to restore it if you can - I tried to click "Edit", which now has now functionality :(
Well hang a on sec though - I'm definitely not trying to make you feel bad or anything - everything I said originally stands and this is not meant at all to be a hit at your skills. Yes, two major puzzles so far seem to have extreme flaws surrounding the clues leading up to them, but that doesn't negate from the rest of the game and your hard work. It just shows that you made your first attempt at a MUCH larger-scale game this time around (and were mostly very successful) and maybe there are some kinks that need a little fine tuning in your puzzle designing process - that is all. I would also maybe give some more info when examining things too (i.e. Evil Stitch and the Fruit - both areas had the clues if you were looking/examining). The starter page listed above tells you to rely on "Exam" alot, but Exam very rarely gives you anything that really helps unless you already saw the oddity yourself before even examining it. Pixelated games like the ICOM (and ICOM-inspired) adventures should be very careful relying on that in my opinion.
You haven't disappointed anyone if you take a look at the overall product you've created. You guys kicked a** with the game interface, soundtrack, extra features to make it more user-friendly, etc. Your game "engine" is beautiful, hands down. Every aspect of the game outside of what I've said about puzzles is beautiful to be honest.
And again and always keep this in mind, these are my opinions only - you did this for us for free and you went WAY above and beyond compared to the basic interface that Infested had. It's just the wandering in circles with no hints from examining things, etc. - there's a little too much of that in this one.
Sorry if my previous comment came off that way to be honest - text is hard to convey sometimes (this is a great example of why I never, ever handle personal topics of high tension via text either), but don't feel bad at all. I've simply played a TON of these games (I finished Shadowgate Re-imagined on both Apprentice and Journeyman without a walkthrough - i haven't played the hardest level yet), so I just have a lot of memories of ICOM-esque puzzle structure for comparison.
/Edit - the puzzle I was talking about was the rock wall. There is absolutely no way I can see to have figured that out without basically clicking every pixel on the screen. This is a key area where "Exam" fails heavily. Unless you click the exact spot intended, you'd never know you're doing anything wrong since the spell also works on the incorrect answer as well. Leaves the player believing the incorrect answer is the correct answer once they find something else which is not actually there.
