Well, his new project "Route to Cuckoldry" shows some promise, if he listens to the audience at least a bit. It has the same graphics, but with some improvements, the English still has some major hiccups (and I say that as a non-native speaker), but shows some uplift too.
The concept is comparable to this one, but suffers from the same problems "Newlyweds" has. The various storylines are actually not bad, with real differences between NTR, sharing and monogamy, but some elements are disjointed/out-of-the-blue (which is not bad per se, but should not be just snapshots)and the biggest one, problems with tying together the various event paths. For instance, in "Newlyweds" in one playthrough I shared her with some men, but the kid is definitely from the MC. In the Epilogue it said the MC wonders if the kid is truly from him or the wife´s boss, but it is absolutely clear from the playthrough the baby´s Dad is the MC. That should not happen. But these bugs could be repaired.
If this Dev calms down and does not make further short-circuit-desicions when something does not work out directly or the feedback is not to his liking, then his games can become interesting for the sharing and the NTR crowds. Even the "vanilla" crowd, since unlike some Devs, Dedagames really makes NTR avoidable.
