Solid game so far!
Only concerns I have at this moment is that when fast traveling or during cutscenes it seems you revert to human form, at least with cutscenes it should go back to beastform after its done? I obtained both soul gems without getting locked into the respective beastform, so my leveling of the forms was behind the curve. I like doggies! Slime pet doesn't seem to do anything, but I figure that is in progress. Some events/cutscenes may be fun to have slight variations based on form. The double monument area, aside from the credits, seems like it could be a mid/late/end game boss fight spot, maybe even for an upgraded version of the two respective forms? The chest in the area outside the Fae shrine is impossible to get, even when I do it right to jump off the edge and then air dash I can never end up being high enough to land on the platform. While I agree with others that the fight against the Fae Prince is hard, all it took was some grinding to max level and proper equips from Goblin Store and chests in the forest, so I feel like you may need to give a hint or two to players. It would be nice for each form to have a passive non combat ability, I know the slime one seems to be able to use grates, wolf form perhaps for climbing or slight movement speed increase? In the end I don't know what you have already planned, but I think it would fun to play again, if changes to game require/force restarting, I did make a few mistakes that caused me to have to grind more.
