I think this had the potential to be number one
This game is amazing from concept, but when it's done to the point where more than 95% of the people are saying hay it's WAY to hard, yet it doesn't get fixed, then it gets a low score. I loved the game till all of a sudden it was just overwhelming, and i took your word and upgraded my slingshot, while it did help, it didn't help me enough to get any further than uprading the other things.
Beat the game...
Not going to go for any special achievements. The gameplay was overall just too repetitive. It was unnecessarily hard in the beginning, but once you get access to explosive and freeze abilities and at least one sling shot upgrade, the balance shifted to the point where I took practically no damage from waves 12 to 19 altogether. Wave 20 was also trial and error. Though I beat it at my first time there, you can't really expect the player to know what to do on a whim...
I suppose it's always difficult to find the proper balance in these things. The order of the food unlocks could also be improved. I'd suggest having a spread ability first and then a pierce through, because most of the difficulty relied on the fact only one enemy could be hit at a time.
It's a fun pass time, but there isn't much to separate it from the crowd.
Way too hard way too fast
I understand that these games need progressive difficulty curves but yours is way to high.
Fix it out drown in low scores
Scaling issues.
It's tricky but crucial. It's not really a good idea to hit people so hard so early on. Despite the fact that yes there is a tutorial it still takes time to adjust. So when I get hit by ten cats at a time with no money to buy a slingshot upgrade and barely make it past level two only to get absolutely mauled in level three... it's a little steep don't you think?
It's sharp learning curve and for some reason I wasn't able to place the ammo I unlocked on any of my cats (tutorial didn't explain that did it) it doesn't make me want to explore a rather standard game despite it's bent sense of humor and cruelty to animals.
poor cats
gameplay is ok.
if you changed the ammo to something else than cats and reduce the difficulty i would probably like it more^^
