Well you definitely made it harder. Liking the new difficulty but cant seem to get past level 5 no matter how hard I try. Enemies move to fast and you cant move the archer from one side of the screen to the other fast enough to kill them since by round 5 you need to hit some enemies 3 times (and thats with the first attack speed and attack damage upgrades). Didn't experience any glitches however and I think the new fixes are good. Just need to look into multiple levels of difficulty and tweak the hard one a little so that upgrades are more balanced with enemies increasing difficulty. Also a save option would be nice. Looking good though! I will be keeping an eye on this one. Keep up the good work.
Same thing with the glich at the top of the screen. I like the concept but you might make a few difficulty settings. Was to easy after getting just the one damage and speed upgrade. Looking forward to seeing the final product just needs a little bit of work. Good work so far!
