Visuals and polish were on point. Love all the little animations and effects you guys fit in. Projectiles and hazards had good readability. UI work in particular was great. I was very appreciative of the controls being laid out very clearly. Sometimes jam titles lack that and it can be a bit harder to get to grips with the game because of that. Getting extra game juice in on stuff like health bars is a small detail but it can really go a long way, happy to see it in a jam title.
If I did have critique it would be that I didn't really feel any incentive to use Ionian (Melee) mode at all; Dorian (ranged) was essentially the same as Ionian with the caveat of slightly reduced damage but offered similar damage with far less risk. Combined with the gravity well effect, kiting enemies becomes pretty trivial, and the dash doesn't have to get used much either. Depending on your design goals there are many ways to address this problem (if it even is a problem) so I'll leave it to your discretion.
All in all it's a solid entry with a lot of potential for a full release. In particular I'd love to see more modes implemented and find ways to move players to switch modes more frequently.
good job yall
