Honestly, this astonishing..
The home-made audio creates a really nice atmosphere, and sets the tone for the hyper-polished text lore coming through nice animations.
The sound effects suit perfectly everywhere, pixel art mixed with high-res text worked like a charm.
So that's what I thought your game was about at first, efforts have been put into details but something else should be missing.. But no? This is an almost complete game!
Puzzles and new mechanics are very well introduced, it might take some time to realize that there is some real-time aspect to it in the first levels (but it shouldn't be made more obvious to me, because we figure it out).
The game is hard, but it's fine, balancing through levels is well done also (difficulty increasing correctly).
So, I finished it, and I want more..
Can't believe this is actually your first game jam ever, well done, I really hope you keep doing some!
(This was easy to rate)
