ok heres the the things you need to fix
1.difficulty, after level 10 the game becomes very hard, after level 20 its impossible
2.chickens are worthless, they need to pay more money, to make up for the lost ap.
3. not enough wepons for each type, for example is see a lv1 machine gun, and a lv8(was a different level) the difference in power was micoscopic.
4.should be able so veiw more then 1 recuit.
Last is my ideas for the game
1.add multiple guilds. and ranks for the guilds. a guild shop, and quest bord.
also add castle upgrades that change its apearance.
And dont be discouraged by everyone, most of them dont know what there talking about, saying that whats the point in multiple save files if they just overwrite them. they dont your mistake was you didnt change the save file, you left it on the first one.
This is the best defense game ive ever played (and ive played a lot). Im hoping you make a second one, but this time make it easier, more rpgish and have all the bugs sorted out.
This game is really glitchy, but to make tetris into this, is bound to be. I'm hoping you make a second one glitch free, and include battling bosses. I do have some ideas for the game, first make it so your not going up, but all directions, the wall jump would make you go into the pit if you used it in this game. Also make the tetris fall in a pattern.
