Pretty fun game :)
Visual
Visually it looks pleasing, but it's not really consistent, it would've been nice to have drawings of coconuts instead of photographs.
Audio
Nice BGM, really calm, but it misses some SFX when you successfully hit the key :(
Tutorials
Well no tutorials, it would've been nice to explain what to do, in how much time, etc. in game. But I'll give you a bonus point for writing that in the description as it's an HTML5 game.
Gameplay
- Nice gameplay, easy to master
- It would've been nice to have a "punishing fail", when you press a key not shown on screen.
Fun
Quite fun, but rapidly repetitive.
Bugs
Once the game is over, you can still press remaining keys to increase your score.
Letters overlap, but it's already been said before.
Theme
Well, let's say I'm surprised by the letter, I'll give you that point :p
