Very nice for a first game! I think something went wrong because I “won” by dying on the spikes before the slime? But it’s nice to see how you used the scaling mechanics differently.
I think we shouldn’t have ressources for the spell, or only one for both of them. And the red up-scaling spell should have some use :p
I really enjoin you to polish the game, maybe make a full tutorial level and up to 5 actual level because you do have quite some mechanics. Maybe put less levels of scaling too it would make the game smoother. Anyway, great job!
