There is no hacks i think. It's easy to beat game in 4-5 days. I beat it in 3 days. Can in 2 , but i need about 10-20 tries. 1 day is impossible,because of low speed and low damage, it will take about 20 minutes to dodge all bullets and kill all bosses.
it's the best gаme i hаd ever plаyed .)but needed to get some improvements. like showing stаts of units аnd weаpons.) it's good thаt this gаme is very chаllenging..i love it. 10/10. with some updаtes will be like 20\10 ")
Lol.Lol...that game need to be on 1st place > )) some people play 1-2 minutes not like and go out =D it's not right )) this game is best )) but need to be more longer with new monster bosses and weapons :))
