Update on the Space Elite Force post I made...
Done with all cheesemos. Total time 114 minutes (including an extra 20+ minutes replaying infinity mode).
I think there are 7 stages.
Hardcore mode just cuts health in half and you have to start from the beginning if you die.
Infinity mode is what it sounds like. You can buy upgrades when you die. It's fun, but either the game is crap at pulling enemy patterns or it just liked throwing a certain enemy set at me. I didn't count, but it was the same group of enemies for at least a couple minutes.
I kept having slowdown issues where it seemed the game was freezing while loading a sound or something, but I don't see any complaints in the steam forums, so it was probably some weird bug on my system. It's why I wound up dying during my final run of infinity mode.
There are two types of 2x powerups. One for upgrade points and one for score. There also a health powerup that restores some health.
The ship speed is fine.
There are some baby's first bullet hell patterns in earlier stages.
I still say not worth full price. Unless you're super into shmups and/or getting highscores on leaderboards.
