The wasn't very fun. 

It actually looks amazing..

I know you said its not a finished product... but I'm glad that you published it anyway.

the idea has a lot of potential and to be honest its a really cool.

It's a good concept and not that badly implemented! I'm not gonna point out the obvious but what especially threw me off is that the particles you lose over time look the same as others, but cannot be recollected, which makes sense I suppose but was still confusing.

Hm, it’s not as garbage as you think this is, looks like a hole.io clone but with a different yet better idea behind the walls.

Here’s some stuff I think should be improved:

• Collision (Bounding Boxes aren’t much active)
• Blackhole sprite should go behind the particles
• Add some instructions! (Had no idea what to do ’til I saw the player sprite)
