The idea of a retro prehistoric hunting and survival game is a great concept. The DOS-inspired style gives it an old-school arcade feel, but the current presentation is very minimal and makes the prehistoric theme difficult to recognize during gameplay.
The game would benefit greatly from a short instructions screen explaining the controls, the objective, how to attack, and what the player needs to avoid. I had to guess what to do once the game started.
I would also recommend improving the visuals with larger and more recognizable characters and dinosaurs, a clearer environment, animations, and stronger feedback when the player attacks, takes damage, or earns points. The concept has potential, but clearer instructions and more developed visuals would make it much more engaging.
