Nice game, Buzzwerd! I took a bunch of notes as I was playing... I'll try to organize them into categories.
GameplayYour basic mechanics are fun. Shooting is satisfying. I had more fun with the keyboard than with the mouse.
I really would like to be able to fire infinitely by holding down the shoot button. I also would like a charge shot power up (hold down shoot button for a blast shot).
I like how the bullets get smaller as you spam them. It's a nice mechanic that suggests to the player that maybe they should try aiming instead of spamming.
A scoring/combo system would give me more incentive to keep playing.
The pacing seems to be a bit random, which doesn't always work well for this type of game. I want there to be an intended progression, a build up. There have been times where I start the game and immediately face an enemy that, in a previous play session, thought was a mini boss.
Power up sequences should be a bit shorter. Feels like they interrupt the flow of play.
Like Derity said, some of the power ups (candy) seem to do nothing other than change the main character's facial expression.
MenusIn general, I really like the menus. Clean and simple.
I'm not sure why there is a spinning wheel on your options menu, but I think you should put it on your loading screen to replace the existing loading circle.
The "BACK TO MAIN MENU" option I get when I press ESC during gameplay sends me back to the splash screens that appear before the main menu. I would like to go directly to the main menu (no waiting).
VisualsIntro stage is very pretty. Looks like an oil painting. Love the parallax.
Death sequence is excellent. Very cool animation.
Changes in facial expression are very funny.
Edges on sprites/text is inconsistent. Some have clean/smooth edges while others look a bit dirty/jagged. Should be fairly simple to clean this up, and would go a long way in improving polish.
MusicI enjoy the background music, especially the background music that plays in the intro.
I would like different sound effects for shooting depending on which power up I have. (Not sure if I tried every power up, so maybe you already have this and I didn't notice.)
BugsCharacter can go offscreen at the top of the screen but not at the bottom.
Game crashed on two occasions, both very early on in the intro while using the keyboard.
After pausing and resuming, the background music occasionally stops playing.
Regardless of the control method I choose in the options menu, when I play the game I can use all three control options at the same time.
The changes I make to the key mappings don't actually reflect in-game. I changed SHOOT from SPACE BAR to Z, but still only SPACE BAR works for shooting.
Hope this helps!
