Tickles needs to learn how to hit the refresh button more often
You created an interesting world. I wasn't really invested in the story, but gaining new abilities according to the souls obtained was more fun than sinking skill points in for no reason. And some suggestions:
- A lot of the environment looks nice, but there was a lot of clipping in the walkable platforms where parts of the models would glitch through each other. You can avoid that by making them very slightly taller or shorter than each other, or you can just move them just outside the bounds of each other.
- Using the same stone floor at different sizes looks a bit strange. When it's very large, the texture looks too stretched. When it's small like when used up higher in the decoration, it looks out of place. I suggest finding more types of platforms you can use and tile many of them instead of stretching them out.
- Custom abilities with interesting effects are desperately needed. Even though the way you gain them is cool, I was bummed out to get default spells. There isn't even a reason to use Death Coil when you have Firebolt.
- It's great that you have multiple difficulties, but they all felt easier than they should have. I think it would be a lot more interesting if you had powerful hero bosses which level up based on the difficulty chosen.
- Having strong bosses would also make the game feel longer, because it feels cut extremely short as it is now. I was really expecting at least a boss at the end after acquiring all of the souls as a sort of ritual to combine them.
So you have a good baseline for the map, but now you can fill it in with all the yummy things that will make it feel better to play.
