I really like this idea, and how well it was implemented. In my opinion, the time limit adds pressure to a simple game, and that's good for this game with not so many options, but it would limit how complex your decisions can be , if you want to expand this game further. Some random ideas:
- Bow and arrow to attack enemies ahead on the line.
- Enemies (and probably a necromancer) that resurrects and chases you (maybe even from a previous line).
- Shield to "block" attacks (which in reality would subtract from their hit points).
