Hey there Ronove, I got your game for judging so here are some of my thoughts. The lovely artstyle you chose caught my attention right away, and set the mood for the entire game. The story itself was told well and gave enough clues for the player without totally spelling things out for them, though I do wish there were more flashbacks to show the necromancer's experiences with the skeletons instead of just being told about it. I wish there were more chances to affect the story besides when talking to the water nymph, since I picked up on the relationship issues quickly and wanted to get our poor boy someone safe as soon as possible! But I understand that with the contest deadline you needed to keep things streamlined to make sure it all worked well.
I did have a problem finding the cryptic notes, they were too well hidden! Maybe it was because I wanted to finish the game before time was up, but I only found the 'don't go to sleep' note in the library even though I was trying to interact with anything that caught my eye. While having them shine or sparkle would make finding them too easy, it would have been nice if there was something a bit more obvious. After playing I saw your reply that mentioned the hidden notes on trees, and I would never have spotted that! There was just so much other pretty stuff to look at on the maps and the one tree I tried interacting with did nothing, so my eyes skipped right over that. Maybe clues like spilled ink in the castle or a knife in/against the carved trees would have made spotting it easier.
Overall, the love and care you put into this short game is obvious, and I enjoyed the time I spent with it. Great job!
