Absolutely nice game and intriguing mechanics.
One minor suggestion is that is it possible to make "augmentation glyphs" a plug-in effect instead of a separate spell? For example, by dragging the augmentation glyphs onto "amplifying orb" can make it run in speed/small/heavy mode.
I personally find this is easier to manage than having a variant for each augment.
(aka, spell+aug1/aug2/aug3 that can easily switch between them is more manageable than spell+aug1=sa1, spell+aug2=sa2. In the latter case one needs to manage multiple spells, in the former case I just need to upgrade and manager one spell?)
