Hi, I think it is a very very good game but would like to give feedback as currently the there are some big issues that can easily be fixed. I'm sorry if that is long feedback but I think these are issues I have seen in your previous games as well and that really prevent many people from enjoying your games.
1) Controls: The default controls make no sense (J to attack?) and could be made smarter. There's no reason why the game could not be played one-handed, as 95% of the time we're just moving and attacking with pickaxe. I actually managed to make the game one-handed by doing this: up,left,down,right to arrow keys, attack to shift, jump to up arrow key, and down key to crouch. Since I mapped 2 functions to the same key I had to use a script to add delay between jump and holding rope actions, otherwise it was very difficult to jump from a rope, but after this the game becomes very smooth to play with right hand. Please when you design the game pay extra attention to having smart and simple controls as many people won't try to change them and think the game is super difficult.
2) Boring level design / grinding: There are too many levels, and it takes too long to complete some of them. The first ~5 levels are awesome, each with different backgrounds and new enemies, but then at some point the levels become just the same as the previous ones, with slightly different enemies, and it quickly gets boring. I finished all the levels thinking maybe something incredible would happen at the end and this left me with the feeling of wasting my time, which wouldn't have happened if the game was shorter. Rather than having 20 boring levels, it would be better to have 10 levels with at least 1-2 new features/enemies per new level to make them more interesting.
3) Hentai pictures: the animations are awesome, but the gallery pictures should be displayed in game, not just when you go to gallery, for example, display them when the player gets a game over. Having to go to gallery makes things less interactive, it feels like you're browsing instead of playing a game, and I didn't even realize I unlocked them until I stopped playing. This was also a problem in "Survive".
I hope I don't sound too harsh so here are some positive comments as well :) The animations are awesome, the enemies and traps are all original and interesting to fight, the story is short but very good (love the "Spelunky" ambience), the main character is sexy, and the game has lot of attention to details like all the character movement animations and the funny level descriptions. It's also good that we have a lot of health and that dying is not too punishing so we can still complete the levels after being bullied a lot. Hope you keep up the good work :)
