I Appreciate your Feedback.
I know the Shield For the Templar is a bit annoying but only when you have slow attack speed, when you reach the limit like attacking every 0.1 seconds, the shield always spawns in front of you without stoping your movement. I think in that case the shield is a bit Over power.
I dont know either the problem with the level up that the selection doesnt show... but it seems to be only when you level up for the first time each run idk. And the game slow is intended. Now that I look at it, I think you are talkin about the Level Up selection only shows one or two icons, it's because of how I code that system, I did it all by myself and I struggle with it for a few days, but I think the "Problem" is that sometimes the 3rd or even the 2nd selection is locked because of Relics that you dont have yet, I will take a look at that code and improve it.
Yes, the game doesnt explain you anything about what power up does what, but I like that concept. Initially I thougth of putting like a info menu for discovered Power Ups or something, but idk maybe in the future.
Indeed, the game Starts in Spanish because its my first language so, I dont think about in what language the game should start, but like you said, its not a big deal switching the language
Again, thanks for your Feedback, I will Fix/Balance all this stuff. If you only have played the Templar, go on with the rest, Templar is only the start.
