Okay, I played it agaun and now I have some further feedback, I hope this will help you improve on your fun little game.
I got knocked up in the air again, but this time I waited for the toe to fall, if the toe falls before it has passed the foot, then all is good, but if it lands behind the foot it is an instant game over for the player, which feels off.
Besides that, like others have mentioned smaller bugs or worms or so could fit as better enemies. And I feel like the movement change between leg and lower body isn't consistent. First the leg jumps and is bendable, then with the second leg, both are stiff. I think it would feel more constistent if either it's stiff in every iteration or at least bends a little when connected to the hip.
And last, it's mostly just walking forward and spamming spacebar at the moment, maybe you could make spaceial hitboxes connected to the animations to hit the enemies, then your game could work with a cooldown for the attack and less enemies, but more impactful at the same time.
