First off, the music and theme are really nice - exploring a tropical island is always a good time. The survival guide is really funny and a nice touch- it shows me that you got a lot of creativity and good ideas. I enjoyed exploring the island, but sadly didn't make it so far - only got to the entrance of the first ruins.
The main thing that kept me from playing more is the combat - I feel like combat is too sluggish and lacks good UI/UX feedback. The combat mechanic makes it so that its very much whoever gets in the first attack will do a bunch of damage or even outright win, as the first attack stuns the other person and then makes it very hard to break out of the stun without taking numerous hits. Maybe I'm just not understanding something.. but after 5 attempts I hung up the towel, I just couldn't seem to get the hang of combat and it was beginning to frustrate me.
One of the other issues is the graphics - some aspects of the graphics are very hard to get past, namely the fact that the player and enemies are all the same sprite. It would be really nice to see some variation here. Also, the environment is a bit too simple in my opinion. It would really help adding some more foliage, ground variation and props.
I will keep my eye open for the next update!
