I'll break this down from Positives to Negatives from what I've played so far.
-----------------Positives-----------------------------------
+Runs well
+ Nice sound design for the forest
+Character movement is smooth
+Overall mostly good main HUD design
+Good Crafting and Inventory menu's
-------------------Negatives----------------------------------
- Save feature doesn't appear to be functional, as an option to save never shows up.
- Opening after helicopter crash is a bit abrupt. You go from hearing the narration to rolling on the hill while the dialogue cuts out before finishing.
- The run function does not seem to work, though that could be from the injury you start with.
- I feel like Force should be renamed to Stamina, if that can fit, as it fits more with what the stat entails.
- Next to no options in the Options menu, especially to look over and re-bind keys.
- Hard to tell how fast time passes by, as stats seem to decrease at faster than logical levels in accordance with what can be determined by player.
