Nice little 'Bad game' ^.^ I like it! Definitely going to play it further
Not sure if you still working on it but there could be some small changes to make game a bit more juicy:
- add visuals/sounds to collected items (these which allows additional jump in air), the same for these 'impulse' surfaces. The same for player death * . *
- I wish there are more keys for jump for right hand specifically (Enter key or RShift?)
- menu for pausing the game, with ability to close game directly from this menu (for pc noobs)
- maybe it is possible to do so there is a bit less inertia when player is standing on ground? Currently if you move and change direction, seems a bit too much unresponsive, players slides too much - feels too much out of control. That's probably intentional from your side. But still would be nice to have this a bit more responsive
- wall climbing/jumping is terrible! It's the only one thing that succesfully makes me stop playing this
