Major update .20 the dark shield/acheivements pt 1

Major update .20 the dark shield

added a shield power up after acquiring the dark hole upgrade it is very op. but balanced by the 10,000 cost

also added a tier 2 damage boost was in the game but the button wasnt put in yet, so all the damage upgrades are now in the game for the dark hole

added 8 acheivements to the game, this is acheivements part 1 essentially as i still need to get the acheivement viewer button working but so far the acheivements all popped up in testing.

fixed a few bugs on mobile notably the upgrade menu interface. there is still a few known bugs there and im struggling with them as this is getting posted.

this will be the last update of the week (probably) so it should give a solid 2 hours of gameplay at this point. im starting to look into save systems and that sort of thing.

the updates will continue every week until the game is completed any suggestions is helpful!
