I got to dimension nexus, I couldn't really tell what's going on, it seems to be a turn-based strategy game. I was able to mash buttons again and click on enemies and it seemed to win eventually until level 28, then I think I would maybe have to apply some strategy as it looked like the enemy was maybe healing itself. Potential, but I don't think I have the patience to explore it, so if the secret level is at the end, no, I did not get to it.
Honestly with 2 days I would have maybe just tried to focus on a more short, coherent experience instead of a large number of unpolished games. If you want my opinion, it would be just take the part of this experience you really like, maybe start over a new game with just that, and then if you want to put a story on that, it would feel more consistent. But really you are the creator, so you should do what you think is most interesting!
And yes I did have fun, thanks for making it. As for me continuing my particular project- I'm not sure as there hasn't been a lot of interest, but I might at least try to address the game balance a little bit more if others come to enjoy it later.
