An enjoyable game, rating 4 instead of 5 because of two minor flaws:
Controls can sometimes be a bit unresponsive
The colored paths are hard to distinguish when faded in the lower levels
There's something wrong with the design of a launch game where you can end up with anywhere between $5 and $4400 on a first day launch. Mostly it's the ludicrous way everything multiplies -- purple platforms give you extra money and a huge bounce (adding to your time and height multipliers) but it is totally random what platforms you encounter especially till you buy rader.
Hit a funny bug on my first playthrough -- I closed the browser window during the intro fightt. When I resumed, I was down to just the skiff, which the ghost ship promptly came and blew up... Made much more sense after I reset the save data.
It would add a tactical dimension to the game if you could voluntarily discard power-ups to make room for more, instead of waiting for them to time out.
yep, hot keys 1-5 have been suggested. Seems a good idea.
