Hi! Interesting game idea. I managed to collect a few words and even crafted something=), which felt satisfying. However, the core objective wasn't immediately clear to me. A brief tutorial or perhaps just a concise "how to play" section on the game page would greatly improve the onboarding experience.
From a visual standpoint, I would suggest committing to one style, either fully 2D or fully 3D, for a more cohesive look.
Regarding the gameplay, when generating letters, you might want to introduce some 'assist' to increase the frequency of real-word combinations for the player. The current level of pure randomness can feel a bit overwhelming. You could also try reducing the size of the letter grid to focus the player's attention.
