I liked the central mechanic a lot. It is very smart and combines sort of basebuilding with action elements. Unfortunately the action itself is not quite as fun. The enemies appear a bit too close to the player and there doesn't seem to be much strategy in the shooting.
However it is very impressive that this is a 48h compo game :)
Tight little shooter. I like. Maybe a ^-shaped initial layout would make people more tolerant of the fact that up and down are significant and encourage block placement that will deal with this.
A fun game that I would come back to and play again! I like the building mechanic between rounds, although after a while just pumping up the damage/multishot seems to do the trick. The only problem I found was that the multishot would fire to the right of my mouse pointer, and also when upgrading multishot there wasn't a number on the GUI to indicate how many shots I had.
Very good entry! I liked the principle, although with the correct strategy, it's very easy to win - at the end, my health recharged fully in 5 seconds, and I killed the boss in about 20. I love the way you've incorporated the theme - good game!
31450 points (I beat the big boss on my second go.) Made a floor of heal blocks, floor of normal blocks, and then on this island a little house to recover if I needed too. Loved it!
There is always an appeal to games which give the player a way of expressing themselves - in this case, in how to design your defences. As much as I was trying to beat the waves of enemies, I was also trying to protect the structure I was building (a kind of bunker). It was fun, and I think it has a lot of potential to be developed further.
A bug give me game over -.-
