Much too Hard!
5/10
Graphic is nice, Idea is nice, good Enemies, interesting Elements with Harry and the different things but next to impossible.
Make the Quick Fix Cheaper. I Can't Afford 2000 Creds if i just got 2000 but couldn't held them better off. Make them reload Faster. It's like hes running into the armory getting the ammo and coming back instead of just Reloading. And make the Reload-Upgrade more noticeable and add more Clipsize per Upgrade then just 1. Lock it's senseless to pay 1500 Creds just for 1 more Shot.
Actually... It wold be better to give us more Creds per Kill or make the Upgrades Cheaper but now it is really frustrating with these... oh and the Enemies are too Hard. The most are Coming to the Door without you cold do anything with that. And in the End even with Damage Upgrades the Fist is the best weapon i noticed the Game.
Oh and there are a couple of Bugs. Thirst you cant shot if there are to many Ranged Enemies at the Door. They Shoot at You, especially the Laser Tanks, and you are interrupted the hole Time without the Chance of doing anything.
Then If you are Game Over and start over again in the first Wave are additional given Creds for the Kills from the Game Over Wave.
So in the End... I Wold really like this Game but it is just frustrating Hard. Not Challenging, it is frustrating...
If someone next time tests your Game and you fix it by theyre true Opinion, i think it will be a Masterpiece.
