The game is really nice! The gameplay is well-designed, and I love the puzzles—they're challenging but not too difficult, which is well-balanced. It's clever to leave some chests inaccessible at the start, which you find again when you return to the tent and after getting the block cane. It feels a lot like Zelda puzzles, but in a side-scrolling version, especially with the block cane, which is also in some Zelda games! :) The dark pixel art atmosphere is simple and effective. Adding a little background music would really enhance it! :)
I think the idea of dreams revealing secrets is interesting, but I feel it's underutilized. Could it serve more purposes than just guiding and following the trace of the friend? Maybe to reveal other secrets, for example? Or to solve certain puzzles? I think this feature has great potential for innovative gameplay!
Unfortunately, I experienced a freeze, and another time I got stuck in a platform collision. But I managed to finish the game on my third try!
Really nice game once again! Are you planning to continue developing it? I'd be interested in following its progress!
