Thanks! I'm really glad you like it, and I'm planning to continue the project in the continuation jam, assuming it doesn't do too badly here.
The enemies definitely need work. I only barely got them working in time, so they aren't quite where they should be. Alternate keys for the dash/attack can be done; I intend to offer user-set binds in the future, though.
And I'm excited to hear you found the easter egg. That's excellent!
