This is a pretty cool idea! I like that you were able to create a story and a changing environment around that story. I agree with some of the other players that the difficulty curve is a little rough; I wasn't able to even finish the "easy" mode because of the insane rate enemies spawn after the background changes the first time, but in all honesty, being on a laptop with a (pretty unresponsive) touchpad did not do me any favors. I was able to figure out the (really clever!) health on my second run, but at first I thought that was the clock's health and that the enemies were killing it (not me). Aside from that, though, this is a really fun entry and I like the clock idea. Great job!

pretty simple and easy game i love it

It is really cool! But the thinkg with the hp should have been explained a little better. Well done tough!

Cool game! I really like how the world around you visibly changes as the game goes on, it's a neat way of showing your progress.

Love the originality. Audio and Art was cool too. Easy was still difficult for me though. Good job.

Please play and rate my game too if you can:
