lag and twitchiness
controls were too responsive. i can't stand tapping right to have my guy fly to the right. makes jumping on bullets impossible.
also, time control is a fun game concept. jumping on bullets doesn't fit in at all. changing the direction of bullets is iffy at best. it makes no sense logically of course.
you'll probably respond saying time control doesn't make sense logically either. my response to that is "time control is the premise of your game. it makes no sense to attack that. only inconsistencies with the premise. i'll accept slowing down time, i don't accept you could change the direction bullets were going"
