Addictive, Simple, and cool! Great time waster!
I think any added complexity would stave the challenge from this High Score time-sink. I love it for it's retro feel, yet surprisingly intuitive puzzle-like challenge. Just keeping Red from getting crushed is a challenge on it's own, and when it inevitably happens, he seems to want to land on the one spot that'll make him drown...(or perhaps I've been too patient with the water level to rise to that point.) Either way, every error I've encountered through the game was by my own...accidentally trapping the guy, and having to dig him out against the clock, while some other block descends...there's something just very classic and timeless on the premise, though I know I haven't played this game before. It's very interesting how it handles...I like how over time, the Red block will try to force his way out of a tight spot, which can either help things or complicate them.
Loved the game! I'd try talking to Tom about implementing the medal system! It's not necessary, of course, but it would definitely accrue more hits.
I will definitely return to this game, either way, to shave off some time. Again, it's very cool!
