This is certainly a pretty simple, short and straightforward game that might put off some people, mostly because of frustration and the usage of RTP assets. I think your idea wasn't bad, I mean, you tried to make some more arcadeish and combine it with horror elements, which is nice. Hovewer, the execution definitely has room for improvement. Here are some suggestions:
1. You should consider to avoid using RTP assets, and if you still want to use them, there are some tricks that can help you make the RTP look different and stand out. For example: use different palettes, and not just one, Apply a more limited palette, then aply another one, then add dithering, and you'll get something more unique.
2. I don't think many players are scared of chickens. Some might do, who knows. But some players might find the chickens funny and not scary at all. I'd suggest to use more intimidating animals, or better yet, use something that isn't a regular animal but rather some kind of abomination, mutant, ghost, demon or a killer with a mask or something like that. Furthermore, enemy variety is definitely a must to make the experience less repetitive.
3. Arcade-type games tend to require something to motivate the players, such as a score system. That's not hard to achieve in RM at all, you can use the "text picture" plugin to make that
You're fairly new to game making, right? Your ideas have potential, you just need to keep making more games to get more experience and feedback. It's a process, a learning curve. I'm no expert, and some people hate my games, but I hope my advise can be of help to a new fello rpg maker dev.
I hope to see more of your projects and you'll definitely will improve as a dev! Keep on making games! : D
