Hey there! I'll start off with the points I liked.
I think making the genre horror was quite a unique idea. The mechanic and theme of the box was interesting, regaining / losing health based on whether you're holding the it is a fun idea. Performance is perfect, I have no complaints - the reference to Mario at the end was funny, if a bit out of place.
Apart from that I'll be honest, this game was quite tedious to play. Every time you start the game you are met with an unskippable cutscene and about a full minute of very, very slow walking down an empty road. This seems like an attempt at building atmosphere, but really only serves as a barrier for attempts of replaying after dying.
I died in my first two runs against the first enemies because I didn't realize you could put down the box to walk faster. (this can be communicated to the player a bit better, for example by having them walk around a bit before they pick up the box, as opposed to forcing them to pick it up in the first second and never allowing them to see they are able to walk faster).
After dying, the game closes completely and I get sent back to the desktop. At this point I was already contemplating just skipping this entry, but wanted to give it a chance until I at least got a better idea of the full game.
After figuring out the box mechanic, I died to the enemies half a dozen more times, each time having to open the game, watch the cutscene, walk down the entirety of the path, and get killed by the enemies again. Their placement could be improved, right now dodging them is a frustrating endeavor of maneuvering weirdly and very precisely.
This game needs quite a lot of polishing, but I think with a lot more time it could turn into something fun. But right now, frustration is the main emotion you feel when playing the game. I hope some of my points were helpful, I wish you much success on your game dev journey going forward!
