This is a cute, short game. The secrets are creative, the sound design is mostly default but otherwise fine, the gameplay is straightforward, and the writing, while marred by some grammatical issues, is humorous and easy to follow. Having the big boss fight not be at the end of the game, but rather one of the secrets, is a twist.
I came away from this game feeling like it's average. It's not deeply flawed by any means, but it didn't have any "wow" factor for me, either. Like, the combat wasn't bad, but there are some things that could improve it: fewer useless skills, monster designs that don't blend into the battle back, and enemies that require unique strategies to defeat are some examples. Likewise, the story may be funny, but it wasn't laugh-out-loud hilarious. The secrets are cleverly hidden and I do appreciate the guide at the end, but they aren't very impactful (aside from the one that gives you a ton of experience).
My point is this: you've made a good solid entry. Your next challenge will be to make something that stands out from the crowd. Good luck!
