I dunno if it's a problem with my equipment, but it seems like you have to stop moving to shoot, and re-press a movement key to start moving again...that's not ideal...
It'd be helpful if the collecting trophy descriptions included the phrase "in a single week", since that's how they appear to be behaving (11 emeralds one week, then 11 the next week, did not award the 15 emeralds trophy...)
Even fully upgraded, Red Bison boosts only boost you about 0.2 m/s?
Then again, one or two runs after maxing all the upgrades, I pulled in over $800,000 in a single run, half of which I didn't even touch the controls. So...
Here's a hint that I finally picked up on: Losing a particular minigame means that minigame stops coming up in the random selection. Best bet: Lose all of them except the black block platform jumping one, and the spinning dot/jumping ball one, and hope that you luck into good timing on the latter so that the ball just misses every time without doing anything.
"Running full speed makes you invincible vs. enemies/boulders"...and how do we know when we are running "full speed"?
Also a bit of an abrupt ending...
