Hey vizyn, just finished my run of Teem and, wow. I loved it!
Random Thoughts:
I went through the tutorial and that was super helpful. I think most players might skip that and I felt like its sort of mandatory to understand the mechanics. The only note on the tutorial would be to auto-advance once an objective was completed. There's a spot where I'm following gold circles and they start to repeat and it took me a minute to realize I needed to hit Enter to continue.
Visibility can get tough with all the swarm and enemies and attack lanes but most of it didn't bother me. I did struggle to sometimes find the "cap points" I forget what you call them in the game, but it was fun just attacking and growing the swarm
Visually, I love it. Conceptually, I love it. I haven't played anything like it and it's super cool
Difficulty wise, it might be a little too easy. I was kinda surprised I finished a whole run. You may be giving away upgrades too fast? I felt extremely powerful and the only biome that really got me sweaty was the final hive level with the battle royale style circle closing in on me
I can tell you put in a lot of work on this, I'll definitely be following its progress.
