Disclaimer: I hate scary games so my review may be skewed, because I found it scary.
The good ---
* Really nice music and sound effects the fit the mood * Nice colors (sky, water) that also fit the mood * Nice UI touch with highlighting objects with the orange outline * Really cool and scary vibes * Monsters are creepy (although they are a bit higher definition than the boat / hills so they stand out)
The bad ---
* The scream after losing, feels a bit out of place. There is no point scaring the player after they have lost. * The hills look ok from far, but the texture is really weird when up close. * You restart from the start every time you die, which especially for a jam game, can make the replaying process a bit boring, and missing out on the ending of the game. * (Minor issue) When reversing, turning feels a bit unintuitive. Usually, in steering vehicles, when you steer and reverse, you rotate in the opposite rotation that the one you steer.
Suggestions ---
* There could be a hint as to what is needed to open each passage. E.g. the player could think to himself *"I wish I had a sword to cut through this web"* or *"I need something to open this door"*. It may seem obvious, but may really prevent players from thinking they are doing something wrong, or using the wrong item.
Summary ---
Overall a really good submission, the mood is set perfectly and everything contributes to it. Did not make it to the end (too scared), but it definitely feels like a good base game that can be expanded upon. Could use a bit more polish here and there, though.
Congrats on the game and keep up the good work!
