LOVE the sketch-style art and the strong theme. Music was also very cool. The jump felt a little low and the respawn placement felt a little off (usually spawned too close to the platform/spike combos to be able to jump onto the platform then over the spikes unless I hit jump exactly at the moment of respawning). Also, encountered an interesting bug on Gluttony (RAD boss design by the way!) where the sword animation looped indefinitely and I got trapped moving backwards at great speed. But this is a really cool project and I hope you keep polishing it!
