I’m using Firefox, but I thiink the issue is more to do with my overzealous content blocking settings than the browser, haha.
So, pretty interesting concept, I think it could do with some additions to give you extra things to do during a wave (some examples: having some specific enemy types that prioritise going for you; assigning an input to calling for help, temporarily changing the AI of your closest partner to target whatever’s targeting you; in addition to healing, you can also apply buffs to teammates/debuffs to enemies).
Some nice sfx, but would’ve been nice to have some music, but I can understand that being tricky given the time limits. I liked the spritework, although, have to be careful with the way you handle the resolution, there was a lot of subpixel rendering/movement.
Overall, a nice concept
