Hey this is one of my favorite games I've played for the jam.
Quick note to put an indicator or something in the description telling you how to switch your equipped weapon.
The whip especially is very well put together. Blocking projectiles from the center, hitting multiple enemies, sweeping it around, the length growing. This has the base to be an incredibly fun tool in a more developed game. That isn't to say that this is poorly developed or not fun, but you've got something great here with just that one element.
Fantastic job, I hope you'll either develop this or come up with another fun idea in another jam.
