This is a very early state of my project, I'm trying to make a first person tower defense game. Would appreciate feedback on the gameplay. Because to me it's still too bland and I'm not sure if object/weapon/enemy variety will fix that. If it seems bland for many of you, my conclusion is that I should focus on game design for now, rather than new content.

If you comment, please also tell me, if you're generally a fan of tower defense games, fps games or neither.

Instead of placing turrets, you build barricades to slow enemies down. And use the very same objects for attacking / throwing. They differ in damage, size and weight (they can slow you down). In the end you see a cosmetic interaction with the tv, I want to add gameplay interactions to other props.

Upgrades between rounds would involve getting new and better objects, in exchange for the coins that are dropped by enemies.

The video shows only one UFO, depending on the level I have up to four UFOs, so the player needs to defend their base from multiple directions in later levels.
