Good game in general! I agree with the other comments some kind of support system so you dont commit 7 suicides per level for getting E and R wrong. And also some kind of hint how to achieve the ingame awards would be cool. I dont wanna walk around the game blind trying to figure them out.
The game bugged out completely for me.
The companionen thing didnt work at all untill i reloaded the page.. at this point i already had 140+ upgrades, kinda late tho. Besides i cant get the last 2 upgrades cuz the game started bugging after unlocking all the sqaures in the upgrade tree i wasnt able to move around in the tree so i couldnt get to the last 2 upgrades!
