Ok here are my ratings:
-1: the game don't inovate in anything, only the same upgrade stuff, at least put some damage in our ship.
-1: heartbeat panic wasn't funny, luck that I read the comments before of play, personaly I hate scary jokes and this is the way that the devolopers thinks of the players that support your team, very amusing.
-1: some upgrades indeed make de game worse, we shoud have a opption to turn then off, or adjust the levels.
-1: orverall gameplay, It's boring, the game have a goal of stupid upgrades (that's a start), but I doesn't have any shooter gameplay, just put a stone in the "space" key and continue advacing in the game, personaly I played this one because of the "Armor Games" logo, but this game was a total failure, I hope that you guys don't take the fanboys ratings in consideration for create a "Upgrade 3", just quit with this idea if the team doesn't want to put some effort in the work.
ZERO NOTE!! The game is full of bugs, so badly that you have to stick with the crapy things, the bugs hurt the gameplay a lot, please fix this thing before of release.
I don't know why this game have so many bad comments, I showed It inside of my job and soon everyone was playing lol, you manage to make a good enjoyable game, with some grind and envolve stuff. You receive 5/5 from me and I'm sure that if you create a sequel for this game, the next one will be much more better.
Very good game, you mixture elements of old school games and the new ones, for me youre a genius. Like the people sayed, you should add in the game a option for reset the best stones (without gaining then back of course), my suggestion is for add a ingame book, like a collectible, so we can review the boss atributes and who was that monster that droped a certain iten.
You gain 5 stars for me and I'm looking forward for your next game.
