2 of 3 games

I played three free games found on Itch.io; 

1. Digital Tamers 2
2. Die in the Dungeon (CLASSIC)
3. There was a third one. What was it. Oh yeah: End Date

Digital Tamers 2 has really captured my attention, but Nakia already spoke about that. It's not quite a clone but it is heavily based on Digimon World Championship, and uses ripped assets from other digimon games, without license (which is why it's free). It's a single-developer project, and only the latest of this developer's unlicensed Digimon sequel/update/remakes.

Die in the Dungeon is an escalating dungeon grinding "deck builder" using dice instead of cards. The dice are placed on a 2 dimensional grid that has a few organizational properties which at later stages can affect the dice you place and where. Every ten "rooms", which progress automatically, a tougher boss encounter appears, often introducing a new complication to the dice allocation puzzle, in the form of passive effects or grid/points-value manipulation. Very little animation, but effective. Cartoony, pixelly visual style. Hero is a cute frog, enemies are all moles and rats and bees and etc smallish animals.

End Date is a dating-sim visual novel rendered almost entirely in pastel pinks and blues. Unlike other dating sims, there's only one person to date; a gender-fluid person whom you met and have been "dating" online, and who has come to visit for 10 days. One complication to this is that you have no money, and another complication is that your date is a little bratty - so if you can't do an activity they're interested in because you can't afford it, they get fussy and pout; but if you excuse yourself to put in a shift in your part-time job to get money, they get fussy and pout. Along the way there are a few clues that your date is more than they seem; they appear not to have a lot of common knowledge of North American/European culture  or society. The implication may be that they are extraterrestrial, but they could just as easily be foreign, and I'm not sure the developer thought of this. Interactions were primarily dialogue choices with 2-6 answers on average. There is also an RPGMaker-like mini-game where you design a "dream house" for you and your honey out of premade tiles. 
At the end of the 10 days, in the ending I got, my character blacked out, and there seemed to be some implication of an apocalyptic event somehow linked to the visitor. The mystery entices the player to replay, and it's effective. If I had the time, I'm intrigued enough to try for a different ending.
