The visuals look great and I see potential in this game! I think you may want to focus on the balancing next because I was able to finish the game in like 2 minutes. I also think some of the timers are a bit too long for a browser game. I would say the timers probably shouldn't exceed 30 seconds, as this may lose some of your players. It is up to you though, do what you feel is right. Keep it up, and I hope your game turns out well!
