Howdy Mikomoares,
I played the game to the point where I had all the upgrades and it was good fun. I like the creative approach taken to try and come up with something juicy and fresh!
I think the main issue for me was the balance. It didn't feel like I really needed to do the minigames past the halfway point because there weren't enough enemies coming in to make me need more defences.
That being said I still like the idea and I can see a lot of room for growth which is great!
Well done!
