So, it gets to a point where you can't win. There are 4 "sides" to the portal, you can't see, and the waves are endless. Most of the monsters didn't even reach the portal before the timer stopped.
Also, and this is huge. PLEASE, please add a locator for the portal. I can't keep track of it in the middle. I eventually put my little (quite useless) men in a horizontal line across the board.
Otherwise, it's a pretty good game. I played for like 20 minutes.
Thanks for playing! That's a good point, since it gets progressively difficult over time it could reach an impossible state if you're not able to upgrade on pace with it. I'll see what I can do to tweak that accordingly.
I'll definitely be adding a locator for the portal to help find your way back. Do you think it would be useful to add for the obelisks as well, or did you enjoy the challenge of searching for them?
I would say that once you discover the obelisk, it stays on your map. I mean, I didn't actually enjoy looking for them, but if you had a fog of war on the map to help you remember where you'd been, that would probably be perfectly fine. I'm sure having to memorize where everything was affected my gameplay and I wouldn't just give them the obelisks
