Very well made game and quite fun to play.
I personally really liked the "How to Play" tutorial as it perfectly showed you what to do without any consequences.
Visually it is very appealing and I think whoever made the art for this did a great job.
The controls are very straightforward while still being difficult, I like that.
The sound effects are good and help with the feeling of movement.
The music is nice and calm which fits the game's atmosphere well.
Great job with this game overall, it's very impressive what can be accomplished in 7 days.
