Could be a solid game but it has quite a few noticable issues.
You are able to clip into ceirtan areas of the map.
The camera is super fast and snappy which just makes it quite hard to focus, also whenever you stop holding down a movement key, the player and the camera god back to looking at the right, instead of staying on the movement axis that you were going down.
The arrows do not go where I click with the cursor, they sometimes overshoot, also they have no cooldown or scarcity so nothing is stopping you from just spam clicking them around and killing enemies.
Sometimes the enemies would appear offscrean where the camera cannot see and id get hit when it was unexpected.
There should also be a visual map for the player since most of the game looks quite similar and its easy to get lost.
The music should also have some variety instead of just being a single 3 second loop.
Killing enemies was pretty juicy and nice, that I have to give you points.
Graphics are quite consistent but the standard unity lighting makes it look quite cheap and plasticy, if it was unlit and unshaded with some kind of fog effect, it would have look like 10 times better than it already does, especially with that flat oldschol style.
Also settings are greatly appreciated, but changing the resoultion completely wrecks the UI and where you can click.
Good luck!
