Pretty fun, the controls are responsive and the platforming is satisfying with the abilities such as dash-bounces. The level design is solid and the exploration with cores reminds me of Super Mario 63, basically 2D SM64. The visuals are amazing, the music is good. There's not much to complain, the demo shows a lot of promise. The only thing I didn't really like is 100% completion reward was kind of disappointing, but that might be just me, as I'm not really into card games. But overall, it's a fun little demo, I highly recommend it to the platforming fans.
