Game concept is nice, and graphics are great :)
The gameplay also feels good, but there are a few points that need to be improved to make it even better:
- Make the game pause when we need to choose a power up (I died due to enemies still able to move while I can't xD )
- Make structures fade out when moving behind them
- Make the character 'lock in' when attacking: the game is fast paced so we have to be quick with attacking and moving away from enemies, however when I right clicking then quickly left clicking, the attack goes at my cursor's position at the end of the animation, not where I clicked. Or just maybe make the movement input with keyboard, not with left click.
Overall it's a good game, just needs some polishing :)
