Thanks a bunch! You can press M to flash an ammo overview but this is a quick fix really, I'm simply leaving hud/ui work for the later stages so a good ammo indicator is missing atm. In terms of ammo scarcity though, some fine tuning aside, it shouldn't be too big of an obstacle. Although sometimes one gets quite unlucky with the random respawns but generally if the right weapons are used in the right situations the ammo consumption can be kept in check somewhat. The warmup phase initially is also intended for the player to clearly see what spawns where, so there is no blind searching for ammo pickups.
The flies are definitely what I'm getting a lot of mixed opinions on so they might get some serious rework. They are the most dangerous enemy by far atm but I feel like there's no use working on finer balance until I have more content, especially levels. Thanks a bunch for the feedback, I really appreciate it!
