I really like the portal mechanic, very well made. The time limit makes things a lot more exciting. However, it's also unclear where to go and too much time is spent looking for the next portal over exploring the game- maybe increase the time limit? I also found that the jump was too high and it made basic platforming more difficult than it had to be. There is also a glitch- if there is a platform with retractable spikes, if you stand under the platform and bonk your head on it while the spikes are retracted, you'll take damage despite not actually hitting the spikes. Overall, good product and I'd love to see more of this. If it's not too much trouble, I'd really appreciate a review on our game if you have the time!
