NICE, this game is so cool tbh, & what cooler is that one of you is 11, that’s nice!, i would say, there are some stuff i would suggest :
1- I Would have really liked if there was an animation, going from the walking animation to the dropping sprite, but that’s okay.
2- the hitboxs aren’t the nicest, they are kinda mean, i mean for example, i always hitted the spikes even if i was visually far from them, i would recommend using a Box collider 2D & than modifying it to fit the actual body, rather than the actual sprite edges.
3-it is kinda hard, i couldn’t pass level 11, which may be cause of the jumping, but yeah.
Other than that, i was SO CLOSE to giving it 5 stars, but these stuff frustrated me, i just can’t, but it is a good game, deserves 4.5 stars, Keep going :D .
