Rage platformers/IWBTG-likes games aren't my kind of games but I have to recognized when it's well-made. Kudos ! It seems very innocent when you start the tutorial and then SPIKES. oh let me retrSPIKES :D, okay, I'll go lefSPIKES.... oh dang it :D
I noticed some lag with particul effects (the fires guns ?), it freewe the game for a second and then starts again. Maybe it's linked to the web version ?
