the game is super fun and addective, but it would be more fun if the ninjas had some bonuses each. like 10% period for a certain scroll. or 10% more money per run, it would also more fun if we had a cat spin at the end of each round ( at destroying each gate ). it would also be more fun if the zombies changed each round according to the nature of the round. ex: same zombies wearing white shields in the snow round. or black zombies in a volcano round... it would also be good if there was some upgrades for every ninja ... like sword upgrade or armor upgrades and also if there was a boss round every 3 or 4 gates ... I'd appreciate it if you made few of these things in your next update. game is super fun but it would be even more fun :) Thanx :D
