Overall: A nice little testbed for a potentially great battle system with some real Harold Jam energy behind it.
Gameplay: Battle system is fun and shows great potential but could be streamlined a bit. Timing didn't seem consistent and there were instances where I jumped or dodged but still took damage. Would love to see this battle system extended to timed attacks and enemy attacks where you can only jump or dodge, not both. Would be fun seeing boss fights where you have to play through a DDR song's worth of inputs to dodge one attack. Off-topic tangent, potions instakilled me and that just straight up was not enjoyable.
Music: RTP is RTP.
Comedy: Double-edged sword. Some funny dialogue here and there, and the potions that kill you could have been great if there was some further indication they didn't work as intended.
Graphics: RTP is RTP.
Story: Simple enough.
