Thanks everyone!
Lake, I'll definitely take those pointers into consideration, however I'm quite fond of the arrows, I thought they had a nice effect.
Tails, I'm actually not sure who made them, and I haven't seen them used anywhere else. But you're welcome to use them. I'll PM them to you.
FGR, the video really helps, I haven't had time to make one myself, and my channel is empty and unknown. So you putting that out there should attract a few people.
P3DRO, I've actually gotten some complaints about the spindash on another forum, so if you want to use the classic dash, just crouch and tap shift. other than that, I will make it so the adventure spindash takes some charge time. and the level design, as I said before, is only there to test the engine.
Chaos Fusion, you're the first person to mention the easter egg. And I thought about fullscreen, but I HATE when pixels get stretched.
BlazeFire, I'm glad I could put it to good use.
I'll continue to work on the engine and try to address the issues, I'm glad you all seem to enjoy it.
For everyone commenting on the music, it says the name of the song down in the bottom right corner when you first start the level. The song I used for this level is an instrumental version of 'Renritu'
