As the game goes further the puzzles become "less musical" and more geometrical. The very best thing about this game is that brings a new twist. Exploit that twist and make the puzzles more musical as the game becomes harder.
Beside what others said (lvl menú and counter) I wuold like to see a dificulty setings wich could changed speed (movemente/spawning) of the balls and the randomness of the bounce.
It has no story, no point on going on. One don't know how much left, if there's infinite stages created randomly or there's an end.
Make something that creates the idea of advance.
(that and the save feature)
I liked it a lot!... the strategy is easy to catch making it a nice casual game for casual gamers... obviusly some hard core gamers would say its too easy but its clear that was not your point anyway... I would only add some more information about the birds, it only have the family name right now but the potencial is great... that way it could be a really nice educational game that even can be used on schools... 5/5!!
Its been so long since i didnt play a creative/challenging/well made-puzzle game... its definitively the best i've played in a long time. 5/5 and favorited... a really good thing is that theres many solutions and one can choose doing it just fast or stay to get the diamonds... and the 8bit look sets it just perfectly... please keep on working, hope to see more games from you...
it is very hard to find new TD games with new features... the diferent resources and the manual gathering are very nice ideas... Change the xp system and it could get much better...
It is strange that when you actually do somenthing good, as getting a clue, it makes it harder to get the others and eventually you get to guess the tiles. Mineswiper was all the other way around, always getting new clues as the game goes further on. Other than that its a good game and a new aproach (very rare this days). 5/5
