a)reduce a little the reload of the catapult
b)you should be able to mantain soldiers from the last round
c)upgrades to the soldiers (i'm middle game and they die in one shot)
d)fix the cost in the market for stone and crystal!!!
e)fix the "you are at the first round but i like you then you have won" bug
f)can set the order in which troops appears
g)fix the archers shots
...then, then will be 5/5
Why can't you sell the blocks?!?!
PS: Fix the arrows, they oneshot EVERYTHING -.-'''
PPS: Same bug here, suddenly it came back in construction mode with enemies, but click on send wave button, starting another one second battle, then back to construction mode (I made 15 levels in a few seconds and won the game XD)
Another idea to improve your game. You could give more points if one choose the right disease in less exams/tests. You can also do a Callenge Mode, once one have unlocked all the unlockables: ten disease, and a fixed number of exams/tests to do.
I suggest to make exams cost time: so you must choose which exams are to do before the patient dies.
It will be a lot more interesting and intelligent than it is now.
Eventually... LEVEL 65 BEATEN!!!
You have to use A LOT of pineapples...
Hints: Super monkey? One fully upgraded. The other turrets must be tack (fully upgraded) and cannons (fully upgraded), 1 or 2 freeze(fully upgraded), 1 beacon (only the upper upgrades).
And you have to learn timing with pineapples, too. Believe me, you REALLY have to.
