The graphics looked very 90s era, definitely fits with the Jam ! I felt though that the first tutorial information is misleading the player to only walk past the enemies while the game seems to actually require to eliminate all enemies as their current map placement is too tight to allow for only walking. Or there is a lack of cover boxes through the map. Also, I played on controller and having the walking button on the front makes it impossible to walk and turn the camera. Which on the corner with the first enemy, doesn't allow for seeing the upcoming second enemy. A button such like a trigger, joystick press, etc would work much better for a movement modification. I noticed a bug btw, when the AI is in the stairs, on a higher step than you, they keep on trying to hit you but they keep on failing as the player is too low.
Overall, while I felt that the current mechanics coupled with the level design weren't fitting well together, I can definitely see potential to build upon it to make this a full fledged game!
PS: Loved the reference to Banjo Kazooie on the UI with the hexagons !
