New version on the arcade now
https://www.scirra.com/arcade/shooting- ... v-02-17020
Pretty much everything has been overhauled by now and it's beginning to feel like a game.
I built some new levels to see all the changes in action, the expanded AI, the collectable weapons, the refined camera.
There's one more killer feature I decided to bring in, to enable a less linear experience and I hope to start working on it soon.
That said I might have rushed this upload a bit, I found a few visual glitches in the version, but I should get that fixed fairly quickly.
