I have to hand it to you, I actually love the look of your game. Really keen on the menu too. Tutorial's wonderful, but you need to put in something to warn the player of fall damage as it was not a pleasant surprise when I found out as I played through the game. You're able to hit enemies/barrels/items through walls, is this intended? Drones seem to drop nothing despite being spawned infinitely from above and that's a bit disappointing. Movement's pretty great, although I feel like you're constantly on sliding on ice with how much you tend to slide before stopping.
There are some issues like the hidden objects I'm currently standing on. Nothing else that I've noticed unless you count drones getting randomly hit by frogs/chameleons/wolves. Drones also seem too weak given all it takes is a single wall to 'outsmart' them, maybe some directions for them to check one by one around corners or even use the actual ricochet mechanic that is in-game and have them shoot at an angle to hit the player behind a wall/obstacle. I'm guessing levels are randomly generated too so you might want to look into that given the amount of invisible objects that spawn and if you're going to tell a story with your game, don't use it at all and handcraft levels yourself. Best of luck.
