I liked it. Very dynamic game. You are great, you really managed to make purchases a part of it. Purchase redefines the gameplay - this is very good. Excellent visuals and sound.
When you get the hang of it - it's fine, hang on the wall and shoot back. For me, a level with one enemy and a bunch of obstacles turned out to be impossible. I needed control over the character's movement and precision movements, i.e. the grappling hook should have less power.
Ui does not adapt to the screen resolution! Hint for players: Set the browser scale to 100%. Reload the page. If necessary, switch to full-screen mode or back. Then, you will probably be able to rate the game. It took me a long time to get to the gameplay.
There were also some lags at the beginning.
Purchases are buggy. It seems that when I bought the first one, I could neither buy nor exit anything else. After buying everything with one button, I can repeat the purchase of everything separately. Purchases are not saved. Maybe nothing is saved in the game at all.
