Hey, I sent you this review on discord, but just wanted to post this here for others to see.
The first thing that caught my attention was the art. It looks just like a classic gameboy game. Also, the way the blob transforms into a heart at the end of each level? fucking adorable. I love the art a whole bunch.
Sound design is great too. it meshed well with the art. I love the little sound it makes whenever he's hit by the bullets.
gameplay is solid. only one input button worked for this game. the puzzle elements were fun. none were too hard that I couldn't figure them out after just a couple of attempts, so great job on the difficulty curve for that. the entire game was a tutorial for the game so whoever managed to do your level & puzzle design for that deserves a pat on the back and a cookie. all of it is extremely well done and balanced.
I don't have a whole lot to say but that's only because everything just meshed so well together and your game is so good that I'm just not sure what all to really say about it beyond, this is a goddamn good game. I was actually surprised by how much content it had, considering you had only 48 hours. it feels like it's own full, short, standalone game. you did amazing and you should be very proud, you did amazing.
