Group 2:
I don't like not being able to jump and move-- it makes movement a tad tedious. I also think a sound effect on jump would be better if you replaced it with a sound effect on landing. It's a bit too cartoonish for the aesthetic. Speaking of which, I like the aesthetic-- it's kind of a horror-like platformer with what looks like an originally-made background and hyper-realistic hearts. I could see such an aesthetic existing in a real game, and it's a cool combination. Overall, pretty good
