Things I liked, Honestly I found your game super charming, the minimalist art style really did your game wonders and I felt the at the controls and everything about it was super smooth. I love how you managed to squeeze in narrative into this with ending your own brother and then having to save him XD.
Things I didn't like, if your going to have high up jump platforms bare in mind that the player needs to at least see themselves when they make precise jumps. Not the worst thing but definitely something to bare in mind,
Overall I think you should be really proud of your game! Hope to see more from you in the future (PS. I found your secret heart stash ;) ).
