Thank you for the feedback.
Our team consists solely of computer science students, so unfortunately, we're not incredibly skilled at pixel art. One of our group members has delved into the world of Aseprite and has created almost all the sprites themselves (others come from the Unity Store). Many sprites were used as placeholders, and we're not satisfied with them ourselves.
Regarding the NPCs, they currently have a placeholder skin because we couldn't use highly scaled 64x64 sprites, and at the moment, we're not investing our resources into appearance. However, we'll refocus on this aspect in the future.
A tutorial/cutscene to explain the world is also in work.
The NPC pathfinding bugs have only become a problem since this build - everything works as intended in the testing environment. We need to look into this more closely.
Additionally, the dungeon will undergo a complete overhaul. In the future, enemy spawning will no longer be hardcoded, thus eliminating the issue of them appearing directly in your face when entering a room.
We've noted the remaining improvement points and errors. Thank you very much!
As you mentioned, it's still a very early stage in development, and we're striving to improve it. ._.👍
