BulletHell Adventure After seeing all the positive reviews, I almost feel bad about posting this cynical review.
It's not terrible, but playing it feels overly generic. You have a typical couple separated by a typical monster/bully/alien and have a lad fight tons of similar looking enemies that receive HP buffs from world to world. Most of what I dislike comes from relatively minor details, but said details quickly add up to create an unpleasant experience.
There are some good elements. The backgrounds are pleasant to look at and the don't distract from game play. The soundtrack is upbeat and peppy, though it gets annoying after a while. The player character becomes extremely responsive after an upgrade of two, though it deteriorates as the level advances. I also enjoyed the little changes to my dragon as I purchased new upgrades.
At first, I thought the coins were bullets, so I actively evaded them. It wasn't until the first level ended and I saw the gold tally that I realized my mistake. Some indicator, like a brief arrow pointing at the gold labeling it would have been helpful.
Instead of receiving higher grades for killing all the enemies quickly or not getting hit, it comes down to collecting power-ups, which mostly requires having just enough upgrades to clear the enemies blocking the stars, but not too much so that bosses don't die instantly. Sometimes I have to grind, not due to the level's difficulty, but because there are 12 tanks of enemies that require 30 shots EACH to take down. Some balancing is defiantly required, because most players loathe doing it themselves.
I already HATE laser enemies, but their ridiculously subtle to nonexistent tells make the ones in this game unbearable. The first one changes from red to a deep shade of pink. If I were color-blind, I wouldn't be able to see the difference. Then the foe turns white when being fired upon, making it impossible to see its attack coming.
The first boss, as far as I can tell, has no warning for it's laser aside from the dialogue in the beginning. Some hint, ANY hint, like a glowing effect, would be greatly appreciated.
In the end, I find this game mediocre at best. However, I do see some potential. I noticed some interference in the music and dialogue, but seeing that you used what you had, I won't hold it against you. You have some skill that will hopefully transfer into your next project.
Until then,
