As there's no comment section in the game page I'll be posting feedback on here. There's absolutely zero player skill involved in progressing through your game as you don't allow the player to do so with the current controls. You're only allowed to push the hamster a set distance in either side in a hazardous stage in which those hazards are determined completely at random be it position or type. At the very least you've seem to have made some appropriate collision boxes/hitboxes except for one thing. If a single pixel of my hard hat touches a spike I'll instantly lose it(this is fine) yet if I'm flying hatless I still retain the same hitbox meaning near misses become instant deaths. Unfortunately that doesn't matter too much because this demo of a game is governed by luck and most likely luck alone with very little meaningful input from the player. I'm assuming this is a future mobile game given the nature of it, and despite having cute costumes and a focus on a cute character it won't cut for anyone else. Regardless of your decision to make a mobile game alike(?), I wish you good luck on fixing and improving your game.
Here's also a 'good' run I have had which was attributed completely to luck.
