Honestly, really interesting game, from the (admittedly short) time I played, there doesn't seem to be much past upgrading your towers, but I still had fun playing it.

I’m a huge fan of tower defense games, so my interest was piqued by this entry! I think it could use quite a bit of polishing, but conceptually I liked the subversiveness of buffing the enemies, and things like the paladin demonstrated you had some creative ideas that could keep shaking things up! I think I would’ve introduced mechanics more slowly - perhaps as rewards for defeating each baddy. Also, it would’ve been useful to see which baddy we were on out of 10.

I liked how the baddies used damage fields - kinda FF-like! Although since the player doesn’t control the minions’ movements I’m not sure it actually impacted the gameplay at all.

I find a bug: The Spawner Core don't cost spheres to buy upgrades.

Once I figured out what was happening and that the minions were on my side it got more fun. I think you have too many upgrades to stick on just two buildings, I would make some more and spread out the upgrade tree a bit. There's no feedback as to how strong your minions are, so you can't see how the changes in your towers really affect their health and weapons or whatever, which makes optimizing your placement kinda guesswork. I think a grid system for tower placement would help a lot too. Once I got all my towers set up and explored all the upgrades, I had no idea how many bosses I had killed so I quit.
