"YOU
WON"
I think you actually win when the 12th wave starts (unless you count the 0 ;) ), not when it ends. I did not check my score, it might have been something like 5400, I think that's what it was the last time I took a look at it.
I had ton of fun playing the game, it took me quite some tries to finally win. I refined my strategy as I went further and realised where all the enemies would come from. I always feared some wave would come from the 4th direction at some point, when I was pretty confident it would eventually not and that there are exactly 3 entrances (or at least when close to the orb the enemies follow only 3 directions, but I think there are 3 entrances), no more, then I placed 2 arrows traps on the more open place in each of the 3 directions that I upgraded twice (among the 6 there's 1 I upgraded only once for a lack of money) and I think I did not lose any life during the winning run, I attacked a few big guys at the end but I would consistently win now. I think I know the map and the placement of most crates by heart at this point.
The game looks, sounds and controls fine, no problem, the vortex pixel art animation is pretty cool especially, but gameplay sure is where the game truly shines. The tower defense basis works fine, the set of traps is good enough. I like that you can directly hit enemies, not only it's in the spirit of the context but I liked adjusting my way to deal with the current wave this way. Same with looking for resource, I enjoyed trying to remember the map and thinking about optimal routes, I like that you really took the time to adapt the concept so that the game is also a traditional crawler kind of, it's more than just a first person tower defense game. Finally, and possibly one of the most important things to me, I think the difficulty is perfectly tuned. The game is mostly fair (you need to play to know what you'll really have to deal with, which is fine to me) and winnable but it's not easy, which is great.
This is a super cool entry, thanks for sharing.
