The first time I played this game, I was impressed that there were still people able to come up with new mechanics for a Bubble Bobble-style platform game focussing on defeating multiple enemies in a single attack. As I played it more and more, I also got frustrated with the awkward controls, and I also came to relaise that the game's real focus is figuring out the exact right way of defeating all the enemies in a stage without dying: a test of smarts, rather than skill. I should really have realised sooner, since the game doesn't have any kind of scoring system, which is one of the two main keystones of a Bobble-like (the other being secrets revealed only through Druaga-esque byzantine methods).
So, you're a rogue cupid who has been causing havoc on Earth by setting up ridiculous couples that don't fit together at all, and God has seen an opportunity to kill two birds with one stone by sending you to hell to bring peace there by making all the demons fall in love with each other. How this actually works is that you shoot an arrow at an enemy, then shoot another arrow at something else, be it another enemy, or the wall, ceiling or floor, and the two will smash together. If two enemies smash together, they'll both disappear, as will any enemies they hit on the way to each other (does this mean they all became a polyamorous unit together?). If you hit an enemy and an inanimate object, the enemy will fly towards the object, and receive damage based on how far they had to go. Hit two inanimate objects and a temporary trampoline will appear, which is necessary for getting to places slightly out of reach of your normal jumps.
It's an okay game, the biggest flaw is its controls. Everything feels very awkward, especially jumping, over which you have no control after leaving the ground, with all jumps being an exact distance. Of course, I eventually figured out that it is the way it is because it's a puzzle game, and if you can't make a jump, you're meant to figure out a different way to get to where you want to be. The problem is that I just can't get past the fact that it looks like an action-platform game, and it's so frustrating that it doesn't work that way. I guess that's more my fault than the game's, though.
Even with that in mind, I find it hard to recommend Dogimegi Inryoku-Chan. It's not very exciting to play, it's even less exciting to look at and solving the stages isn't at all satisfying.
