Even with that annoying lvl cap thing, this game deserves 5/5. I want to play with friends instead of bots. Maybe you can make raid-type thingy for us? It will be awesome!
I really like this game, it has got great gameplay and storyline. I know that, I should rate it 5/5 but I can't... It's only "about 20% of the full content of the game". But I really want to play the full one. Because it's only 20% of the game I can give only 2/5, maybe it will make you think about uploading the full version (I hope you will). Sorry, Devs, you've done great work but I can't let you ruin such a great game. There are many players that can't donate even 1$ but they still want to play.
Proper co-op is on the way. Your 5/5, support and kind feedback help us get there faster :)
