I really like the aesthetics, the game looks very cute. It gives off a sorta valentine's day vibe with the boy and arrow as well. Great use of only one sound effect as well, it didn't detract from the experience at all only having one sound.
That said, I'm not a fan of the gameplay. Using only space to jump and shoot is an interesting concept, but it ultimately just doesn't work out. The game is just awkward to control and it's easy to mess up, which combined with checkpoints being rare(unlike fellow autorunner Blockade Runner) made me want to stop playing pretty quickly. I feel like the game would have been better if the one button concept was just axed in favor of space + mouse controls, it really holds the game back.
Still, for being made in only 4 days by one dude it's still impressive
