Stylistically I liked this one, but the movement is a bit too janky. Like it seemed for some of the speakers there was little to no options for avoiding the projectiles in the more cramped areas.
The visuals were decent for a SBIG game, though the lack of an attack animation is kinda unfortunate. The overly noisy footstep sounds I thought were funny, and the various songs being played were fitting.
For a first game jam this isn't a bad effort, the game runs well enough, and there'sa defined fail state. Though admittedly a "Restart" button on the death screen, or even just having the game automatically restart would be nice rather than having to close and manually relaunch the game. Though that's the kind of stuff you start adding to games over time as you learn and improve, and for SBIG it's not the worst thing.
Good job!
