The Tower re-skinned

Literally copy paste ai slop job of the tower. Donโ€™t do it. Cash grab at its finest.

No limit

The one thing I love about the game is there's no limit to how much you can play in a day. It is an enjoyable but the limitless is peak. ๐ŸคŒ๐Ÿผ

Not my cup of tea.

Iโ€™m a weird player that likes it a certain way. I paused the game just before I would die and ended the round before being taken out, but it said I was killed by Basic which upset me because I ended the round before I could be killed. I like to think of the end round option as using a teleport tool that lets me escape sticky situations. I tried another run and when I ended round immediately it said I was killed by: -, so then I was like this is pointless, I like it when I can do a perfect-save where I never die to enemies because I always avoid the final blow or something.
