yeah sorry about that, there shouldve been some sort of oneboarding or tutorial for the upgrade menu and point system, and yeah we didnt have enough time to add sounds, its a bummer really because i think SFX's with the VFX's would've elevated the game a bit more. Hopefully after the game jam we will start working on that.
Thank you so much for your kind words :D We will try to make it as addicting as possible ;)
