The characters are so annoying to handle 🙄but other then that it was fun and engaging

I liked the idea, great use of the theme.

As it's pointed out, sometimes it's hard to click on the characters. I'm not sure if it's about small hitboxes or a lack of click respond.

Some of the sprites look blurry in the game, like the heart in the title screen.

Good job here!

Top 10 most hated fictional character, number 10:

Cool idea! I love how much variations and mileage you were able to get out of a very simple idea of keeping the two... things together.

The hitboxes for both the aliens and the enemies feels a bit unresponsive and unforgiving.

A very fun game. I was practically screaming that two aliens were going too far apart while I was trying to keep them alive. I think it's creative to use the connection theme to make a game where both characters will automatically die if one is gone. 

One minor critique is UI layers. I noticed the mouse would be behind text or UI elements but it doesn't hinder the gameplay. Also, a timer would be nice but I saw in a comment you had no time so no worries there.

Conclusion: Love is strong and your game was great!
