visual : Decent background and animations but art style is pretty samey compared to the other games you produced. Nice touch with the screen shake when the player character is firing though.
audio: Good music that appropriately sets the tone of the game.
ui : Layout of UI is well-organized and intuitive.
1) Difficulty in pressing skill hotkeys while navigating with the WASD keys (tendency to press the wrong keys while moving with WASD). Also, it is distracting to the player to look away from the player character to check the skill icons at the bottom left corner of the screen, especially when the player has to dodge incomoing bullets.
Suggestion : Change spell selection by cycling through the list of spells using the 'E' key with the icon of the selected spell hovering over the player character. Then direct the spell by right-clicking the spot on the screen.
2) Player movement feels too sluggish; player may feel frustrated at not being quick enough to dodge bullets.
Suggestion: Include an upgrade that raises movement speed.
