The first thing right off the bat that bugs me: The opening letter. The font is wayyyy too small; I can barely read it, due to the style. Some words I can't even make out. Please fix.
Aside from that, there's some mistakes that I've found, primarily involving spelling and grammar.
- Journey is misspelled: "The journy begins here."
- "[Name], You seem all packed up and ready to travel; where are you going?" The Y in You shouldn't be capital.
- "[Name]! Can I have your autograph!" That final sentence should be question, not an exclamation.
- "Remember you can fend off monsters with your sword." There should be a comma after Remember.
- "Welcome friend. I don't really get much visitors in this old tower much anymore." This whole line could use reworking. Something along the lines of this: "Welcome, friend. I don't get many visitors in this old tower very often anymore."
- "I'm the keeper of grounds here. I seemed to have locked myself out of the elevator..." Another awkward line that could use tweaking. You should add a "the" before "grounds" and change "seemed" to "seem".
- "Would you be kind enough to help me?" There's no major issues with the line, but it does sound a bit Engrishy. Maybe change "be kind enough" to "so kind"?
- "Oh, Also..." Also shouldn't be capital.
- "Touch it to end the level and save your save file." Using a word twice in the same sentence generally isn't good. Perhaps change "save file" to "game"?
- In the second level (forgot the name, sorry, it's the desert castle place), after the Delta Orbs are activated, you can't talk to the people again even though the speak prompt appears in the bottom left.
Other than those, so far I've noticed a couple cool things. Knockback on the knight enemies is reduced, making them harder. And you can Delta while on top of another Delta block. Super Squares leave a blue hologram when you collect them, similar to how Super Mario 64's stars turn blue if you've already gotten then.
Also, despite the game mentioning issues with the game and Chrome, I so far haven't noticed any problems with running the game in Chrome.
I'll add more later, I'm having issues with Windows 8 and have to restart my computer to hopefully fix them. Damn you Windows 8, I hate you.
