Thank you very much, glad you like the game so far! :-)
I'm fine with posting bug reports here or at my twitter page: https://twitter.com/@P_Cat_
That's a great help to improve the game and fixing bugs, so thank you very much!
Here's a quick response to the things you've found so far:
- the sword attack through walls was actually intended, although it seems a bit OP and unrealistic. I might change that in the future.
- the water you encountered is shallow water (deep water does not exist in the version you played). It is intended that the player can pass through normally. The only thing that I want to do here is a sound effect when moving through and a small visual indicator (slight waves around the player's feet).
Again, thank you very much and stay tuned for the updated version which will be uploaded today!
