[Accidently closed the tab and now I have to write the same comment again...]
- Visuals are great. There are things to imporve (for example add sprites for the spheres around the player, maybe add hit animation both for an enemy and player), but still. The background is awesome (both in game and on itch page) - looks nice and tiles perfectly + the bugs/spiders/malware scared me at first (especially when there are a lot of them and they are moving towards you) <-- not sure if it was intended, but adds to the game feel
- Audio - music is great, but sound effects feel repetitive. (It's not a big deal, just the thing I've noticed). Changing the pitch of the sound a little every time you play ("AudioStreamPlayer.pitch_scale" property) might do the trick (and if neccessary you can also make multiple variations of the same sound)
- Gameplay. First 1-2 minutes I was like: "OH GOD! THERE IS SO MANY AND THEY'RE HUGE, RUUUUUUUUUUUUUUUUUUUUUN" and it's good. The only issue is that gameplay gets boring prettty fast: no new enemies, no upgrades (only level number goes up) and etc. Maybe this is due to jam's time constraints, idk
Overall - good submission (I like the idea of malware fighting each other on someone's computer, there's definitely space for expansion). Never give up, stay determined and keep learning :)
