Boob dragons aren't for everyone.
The dungeon and its layout its confusing as heck mostly due to running out of time to actually plan a good dungeon with visuals that would let the player know where they currently are. I was struggling so much just getting the game to run without something breaking in the process. Sadly, this meant I had very little time left for designing interesting cave system to delve through.
The general best tactic is to linger just beyond the attack range for the Drakes and either bait an attack or attack and retreat. If you time it properly, you often have no need for blocking at all which lets you get a second hit in much faster. Against the green Drakes this should work very well. They attack somewhat less frequently than the red or blue Drakes do.
Oh, and the sex animations actually speed up on their own over time. Unless I've messed up something with the controls. The player was able to speed them up previously manually as a part of the extra interactivity I sadly had to scrap along with many other fancy systems I had in mind. Turns out being an inexperienced game dev severely limits what you can and cannot, even with a generous one month development period.
Thanks for playing though!
