The character is, like a glass mug? not a lot of personality there.
The first video doesn't show a lot of interest, there's like 6 cuts in a row with the cup moving right and up making the gameplay look repetitive.
Overall look/feel is still very "Unity demo", a lot of what makes the greatest games great is not just their gameplay but the feel and details. Imagine portal without GLaDOS and a low poly un-textured style but exactly the same puzzles. It never would have made the mark it did.
Like I'm looking at the second video and there's these avocado things, are they bullets? enemies? looks like the cup has some large radius, fast orbiting, ball that just erases the avocados. like they don't splat or react, your cup character just lifelessly floats around and stuff is happening, it makes the fight feel sterile rather than engaging.
Unrelated but I found the first video very underwhelming, that is it was very repetitive, and nit really clear what the gameplay was about. Second was better but was clearly written by AI.
Just my hopefully constructive 2 cents.
