Price? Length? Achievements? Having the option to also being able to use the 4 arrows would be nice rather then just WADS. Also CGA had 16 colors, but not at the same time, this makes it more EGA, it doesn't have the CGA look. And typo in one of the screenshots, there is* a stone wall in my way....

is there a trick to getting the shard in the trees?

The item symbol and lore symbol don't disappear from the map after picking them up. Seems like a bug based on the description of the item that reveals them.

heart scanner? like the other two scanners?

Just starting out and wondering if you have any plans to implement a speed up function. I have to imagine extended back-tracking later in the game might get a bit tedious at the current walk speed. Having fun though, reminds me of Castle Adventure a bit....
