Good vampire surviovor-like. Interesting and varied enemies (more so than in any other vampire surviors like I've seen). Nice power ups. Only real complaints is the music cuts out and there are no sfx - and that after around 30 minutes of continuous play, the upgrade speed gets way too low - not sure what balance is missing.
Also, suggestions would be that rather than having the dust meter be a percentage, give me discrete numbers so I know what my goal is in exact terms, and that larger and harder enemeis could drop more 'dust' pieces so that the player feels better for killing them.
Oh, and I wish I could damage the snails while they were zooming.
