This is a fantastic game. I love the sound design. I don't think the visuals are ugly at all, they are great. However, if you did change the visuals that would be a big problem as the game was crashing my laptop as it is. Once I got to the stage where there were no big squares and just small squares, the number of small squares kept increasing all the time until it crashed or I died, and the whole screen was white cuz of all the squares.
Thank you so much for playing it and for your comment! :)
Aw, sorry for the freeze mate, happened the same to me on my laptop. There is a bug I didn't had the time for solving it, on the enemy spawn, that keeps spawning foes until infinity.
My original idea (and future builds) is meant to be more tactical with not so many enemies. And also there is a lot of room to optimization, so it'll run smoothly.
Thanks again! :)
