I stared at The Entity (with 7 characters ... in the beginning, 4 at the end).
The game feels quite ambitious and complete and I had a lot of fun playing it. The introduction and conclusion are cool. I like the choice of a number of characters which will make the (beginning of the) game less or harder. You really managed to create an alien world, between the creatures and their voices, the portals. The traps in the wall to advance to the next level are particularly great. The difficulty is right on point. I like the multiple armor slots and the progressive gain in power via equipment and levels is satisfying, I took my time and by the end my characters were war machines. I like the silly parts with the voices and creatures, they actually fit the alien world of the game perfectly and adds to the pacing and fun.
Neither the wall textures nor the UI presentation are the game best strengths, and I don't specially like the movement but at least advancing by keeping the key pressed still makes it alright in the end.
That's a very cool entry overall, thanks for sharing.
