very fun racer! lotta configurables/unlockables = lotta replayability. Mr Tank's review is spot on so won't repeat those comments, and i agree with all of them.
i will add that i was impressed the first time i saw overhead structures go semi-transparent when i raced beneath them. very nice feature. the career mode is GREAT, as are the save/load features you've included. comes stock with a number of tracks, which is also impressive. haven't yet messed with the track editor so can't comment on its functionality but at a quick glance looks very solid and inclusive! i'm assuming you made the stock tracks with it so i expect it works fine.
1 persistent/repeatable bug to report:
after racing "time attack", when you come out of it (choosing restart? "no" and back to the menu), if you choose "start" while there is no track set (it should have a default map already chosen for you), the game will crash offering error 502 "image does not exist as line 2690". work around = always choose a track before hitting "start".
2 items to add to any "wish list" you might have in the works for a future edition or sequel:
1) additional camera angles. the top-down is cool and effective, but i'd love to have an option to play from other perspectives.
2) an "instant replay" feature is always a big plus for racing games.
i love these kinds of racing games. simple enough to be fun right away, technical enough to give it depth and progressive challenge. a very nice release, MaRo! thanks for sharing!
