First of all, this was pretty great entry for something done in just a one week.
But, on the other hand, I think the rushing might be showing. As in, this is a very complete game, especially for something done in a week. It has several towers, several enemies, it has a story shown, and end, even fully fleshed tutorial. But at same time it does feel bit soulless in sense that it feels like everything was done to the professional minimum standard. Felt like you had came to conclusion that minimum amount needed to make towers feel like having variety, is to have three different ones, and then you did so. Similarly felt like you thought, minimum amount to make enemies feel varied, is to have 3 different, plus big bosses, and so you did again.
It feels same time very professional, and I also like to say that your hunch is right, it indeed feels like exactly the minimum amount to make the game feel varied, instead of not varied. But at same time it becoems slightly soulless in that it feels things are too calculated.
But when putting the calculated feeling, I had fun playing this, and if I wouldnt be such overly tower defence veteran, I would have probably enjoyed this quite much. Due to having lot of experience on Tower Defence games, it was bit easy for me, but then again, I wouldnt have liked a hard one on a game jam necessarily either.
And, as I have played so many tower defence games, it is rare to see anything new anymore, and that was one of the great positivesw to me, that there sort of was something new. The Grapes that had to be collected. Although you could say that Plants vs Zombies for example has the same system already, it is not exactly the same system, since you had to plant the flowers, and then there was this sun or something that kept dropping on regular intervals.
That the bushes were there already, and grapes appeared on random bushes, and you then had to pick them. I would count that as something new, even there is similarity to something pre-existing, and that made me very happy, seeing something new in tower defence genre.
While I did like the simple story, it however didnt deepend much the understanding of bible verses. However, while there might not have been much to learn there, game however implemented the verse into a game very nicely.
I think that all in all, this was pretty impressive game for a game done in such a short time, and cant help but wonder what you could have achieved, had you used another week for it. But very professional seeming this one already.
Oh yeah, one thing that made me a bit of confusion was that since I first choces to look the tutorial, and it had text, then when I started the game, and cutscene had no text at all, that felt bit odd at first. My first thought was that some bug happened actually. But it was actually quite nice to make the cutscene not need any text, but it was for any language.
