The gameplay is really lackluster in my opinion. Maybe some variation or something else that affects your stats would be nice, something more engaging. I still like the basis and where it's going.
This game is great but afew minor adjustments would make it a good 5/5. Pressing escape should also pause the game, and a better save system would be nice.
Only issue I've had with this game so far is the spawning. Sometimes, I'll spawn in front of an enemy and I get killed instantly. Besides that, this game is great for a mobile/browser game.
