I like these meaty shooters, fun and addictive, this is what game jams is about.
I don't know if it's a me problem but the game wasn't at the right resolution, I don't think I was able to see the whole game space because whenever I got the upgrade screen the right and left upgrade panels were cut off.
Once the enemies really started coming the game hit a big slowdown and my computer couldnt handle anymore, too bad was really enjoying it and look forward to more!
