Hmm, this one was a bit weird to me! There's definitely some interesting elements at play here: the presentation is pretty nice with good pixel art, sounds, and animations, there's a bit of a strategic element with limited ammo usage, and it does seem rather charming in some way. However, the gameplay never seems to coalesce into a unified vision or loop, with me getting confused at certain elements like how ammo doesn't reset on death. And then before I know it, the game was already over with me feeling rather unsatisfied and unsure of what the game was trying to go for!
Obviously you have my sympathy because it must be very difficult to make a game in such a short time limit. If it helps, I did feel like the game showed some potential to be something like a roguelike survival horror game. The tomato and corn weapons reminded me of a handgun and shotgun: one being good for taking out single targets, while the other being good for taking out crowds, but being much more rare. Perhaps if the game was randomized and punished you with a full restart on death, it'd force the player to be more improvisational to make it through the gauntlet: they'd have to decide quickly whether to save ammo and avoid the zombies by jumping, or whether to spend their precious ammo to completely wipe them out or at least thin the herd to make avoidance easier. The player could then be given a score at the end for how fast they make it through and how much ammo they saved and so on. There's definitely something in here if it made me think about it that hard!
