fun game! It'd be cool to have rebirths once you make it past the front lines. maybe the game could get harder, but you would unlock certain perks (or maybe a store to buy bullets/grenades?). some other things:
- add a keyboard shortcut for switching between guns and grenades
- add a victory animation at the end
- swap the text hints with a visual (e..g a broken branches/disturbed ground/trash visual in the top left corner)
- add a leaderboard where you can compete with other players
