I do have to ask what is your contribution to this game? According to the asset list, there is very little work - done by yourself. Or at least that i can notice.
I understand that this is a narrative based game, but even then, how does it fit with the theme of the jam?
On to an actual game feedback:
The game seems to be well put together, the ride along gameplay combined with actual gameplay is an interesting take that is not that common. Some may say that there's too many cutscenes and too little actual play.
The aesthetic between the walkalong section and the gameplay section is too much in contrast, the art styles do not fit. I'm sure you could've used one set of assets for both the environments.
gameplay - if you're not lucky to get the movement speed buff in time, you will die. You should probably change the spawn rate or make the monster abilities more scalable by level or stage :D.
Overall, i think this narrative style game has a lot of potential, we shouldn't have too high expectations for game jam games, most of these are masterpieces, including this one.
