I like the cleaning game. The head you control seems to match the hitbox which is very important in any bullethell inspired game, and it´s great that you have arrows guiding you to the goals, else it would had been a nightmare.
But, I do not like it enough that I want to do it as much and often as the game encourage. Even with the rewards, and my equipment dragging my character towards the ditch + the possible punishment you get for not cleaning. After doing it 10 times I got really sick of the minigame, and only did 1 or 2 per level, sometimes skipping it entirely. I think there should be fewer ditches per level. Either replace them with something else for variety, or make the fewer ditches matter more. The cleaning game becomes even more monotonous, after you cleared the dungeon, and you go for your second, identical(except for other layout) run.
I do like that the maid gear assists with the minigame in various forms. I hope you will use that idea with other aspects in the game in the future by implementing other outfits. I do not know if it is a bug, but after I got the full set, none of the melee enemies, except robots, wants to get near Eliza and apply bondage gear. I do miss an option to remove the gear, or some of it.
I understand that this is a very early version of the game, so maybe you already have these changes in mind, but I do think it would improve the game.
I also feel the same with about the untying minigame. I thought it was okay for a short while, but quickly got sick of it, and turned it off.
