I really liked this start!

The MC is bumped onto the monster track of progress and growth.

I enjoyed his funny cartoony thought process.

It's the opposite of Skeleton Knight In Another World, where the main character skeleton starts extremely strong.

I found this one very dull, with the typical-of-the-genre problem that it felt like watching someone else play the boring parts of a video game. Then again, this isn't really my genre in the first place, so maybe its charm is just fully missed on me. A 2/5 premiere for me.
