While I can see the vision for this game, it’s clear that it needed a bit more time for polish.
First I want to talk about the art. The style used on the title screen is very different from the visuals in the rest of the game, which makes the game a bit less cohesive. But it’s clear that most of it was placeholder art, which is better than nothing.
As for the visuals after entering the main game, the actual spritework looks really good. However there are many different pixel densities, which creates some clashing visuals. To avoid this, you should try to ensure all pixel art is not rescaled in engine by drawing all the sprites “To Scale” before adding them. This way you don’t end up with different sized pixels on each sprite. Which helps keep the game looking consistent and professional, even with simple sprites.
As for the audio, the ambient sound does set the tone for the level, however it’s a bit boring. I think keeping the ambient wind/storm sounds could work if you also layered some actual music over the top.
For the sound effects, I think most of them were fitting and helped with clarity. More sounds on enemy deaths and the player taking damage could help polish the game more, but I assume you ran out of time for stuff like that.
Next I want to talk about the gameplay. The general concept is easy to understand, and most of the mechanics are there. However a few game breaking bugs make it hard to progress far and enjoy most of it. Specifically, the stationary harpoon seems to break the shooting, and enemies killing the player doesn’t seem to do anything. Additionally, the invisible level walls make maneuvering a bit unclear.
Overall, I think if the bugs were cleaned up and some balance changes were made, you would have a complete game with engaging gameplay. I apologize if this review was a bit much, but I'm doing this to all the games from this jam as I think critiques help us grow.
