Hey, very cool! Level 20 is quite a feat.
> I felt like the low jump height was holding the gameplay back
Initially I thought spells like (Air+0) high jump would be way more intuitive in a way that you'd be like "Oh I need to jump high, let me grab air quick" but that was hard to put into practice. Movement spells are mostly useless in their current state. I get where you're coming from because I agree, but higher jumps would've made the flight/jump spell useless. It certainly needs balancing there if we were to continue the project.
> the artwork for the main characters is awesome
Haha when I contacted my friend I gave him full creative freedom for the art. I requested 24x32px sprites of hooded mages without legs which seemed doable in a weekend (you can see them in the design document) but he was like "Hell naw". But it came out really great yeah.
I'm sad that we couldn't fully complete everything because the person who did the voice lines actually recorded a lot more, but I didn't manage to put everything in.
