ok so ive beaten whats available and heres my thoughts
1) when your in the tutorial DO NOT CLICK THE CIRCLE it turns out you can buy an egg ending your run as you now have no money to buy protection
2)read the descriptions of monsters you use it can help or hurt that run
3) do not buy the kaiju upgrade it literally blocks 1/3 the room so you cant see
4) the imp mother upgrade only upgrades to +1 then after for some reason changes to a different monsters upgrade
5)at the very end in the endless mode i encountered a bug where even though the round was started it never started
6) all in all a pretty solid start for a new title though i would like to see more added to the tutorial phase so people dont make the same mistakes i did
