Cute concept, very silly capybara and the cursor here to help lol ^^
I was stuck on the second level though. I think the jelly is bugged. I managed to figure out putting jelly on the brick wall, but Capy just phases right through the jelly (I assume it's meant to act as a platform?)
There's some other bugs with spawning items as well, such as if you begin spawning an item with 'trampoline' selected, if you start changing the selection in prep. to, say, a rocket, by the end of the button-spawn sequence, the item spawned ends up being the rocket instead of the trampoline. 

All round solid gameplay and a clever use of the theme. The particle effects used when pushing the capybara on it's skates were a excellent touch. Kept me captivated for a while.

The only bug I picked up is when on the rocket and jumping off too close to the platform, the capybara would become stuck within the platform itself and a reload was needed. Other than that, it ran smoothly.

It was an enjoyable experience overall, well done :)
